Abstract:
Over the last several years, the Web Services model of Geographic Information Systems has been rapidly evolved and materialized. In this thesis project, I have reviewed the current status of integrating the general Web Services technology (SOAP, WSDL, and UDDI) and OpenGIS Consortium (OGC) Web services standards in developing distributed GIS computing. The overlap of the web service model and the technology stack between the SOAP-based Web Services and OGC Web Services indicates the feasibility of integration. OGC has named all core general Web Services Technologies (SOAP, WSDL, UDDI) in its envisioned OWS architecture. OGC has also started putting efforts for the integration by conducting experiments, which include a SOAP experiment and an UDDI experiment. However, these experiments only identified some very specific issues based on small number of testing interfaces and scenarios. There are leading GIS software vendors who have adopted both areas in their implementation. The ESRI ArcWeb Services is a good example, which implements OGC Web Services Interfaces using SOAP, WSDL, and UDDI. In my implementation experiment, Java Web Services Developer Pack is used to build a client of Microsoft TerraService. SOAP messages are constructed to retrieve DOQ images from the TerraService as the background to display ArcSDE feature data. Query functionalities on the feature data are implemented.

Abstract:
The purpose of this thesis is to compare the performance characteristics of Simple Object Access Protocol (SOAP) and Representational State Transfer (REST), which are methods of supporting interactions among Web services. They differ in both context and usage; SOAP is a protocol while REST is architecture. SOAP is a well-developed protocol used in the Web industry and is standardized by the World Wide Web Consortium (W3C). REST is the outcome of Dr. Roy Thomas Fielding’s 2000 PhD dissertation, “Architectural Styles and the Design of Network-Based Software Architecture.” REST is gaining in popularity due to its simplicity, scalability, and architectural dependence on the World Wide Web. Major software companies, such as Google and Amazon, among others, have started using REST. The main difference between the two methods is SOAP is a tightly coupled system, whereas REST is a loosely coupled system; both have advantages and disadvantages. We built SOAP and REST based Web services that performed the GET, POST, PUT, and DELETE functions on a database. We utilized response time and throughput metrics to compare the performance of these Web services. In comparing the two technologies, we found REST was considerably faster, compared to SOAP, because the response times of REST were better than those of SOAP. As an ancillary outcome, we found building Web services using SOAP was easier, due to considerable tool support, whereas developing Web services using REST was time consuming, as it provides no tool support.

Abstract:
The PHP: Hypertext Preprocessor language (PHP) has evolved to a sophisticated mainstream programming language for rapid development of significant Web applications at major sites including Facebook.com, Wikipedia.org and Yahoo.com. Leading software vendors such as Oracle and IBM are rushing in providing tools that bridge their products to PHP. However, we have observed a gap in facilitating PHP to utilize Web services efficiently. This thesis reports our efforts in design and implementation of PHP applications that consume Web services. In doing so, I have proposed a framework facilitating PHP programs to utilize Web services with high performance capability. In addition, a number of Web service standards including WS-Addressing and those in WS-Security are integrated into my PHP implementation. Examples of using various Amazon Web Services are provided with details.

Abstract:
One of the main aims of Component adaptation [Szy97] is to help application developers reuse components so that they can plug-in third party components into their application. This research concentrates on this type of adaptation but in the context of Web Services. Web Services are becoming increasingly popular. Web Services often fit the requirements of being a component, and can be reused in a very similar manner. Hence there is a requirement for adaptation of Web Services just as there is the need for adaptation of software components. There are now quite a few adaptation techniques, but few of them have identified adaptation techniques for Web Services. This approach to adaptation allows for the modification of data and behaviour of existing Web Services. The approach to adaptation uses eXtensible Stylesheet Language (XSL) transformation applied to the message passed between Web Services. These messages are commonly in XML format, hence XSL can be used to modify them. The application of the transformation is guided by a specification written in XML. The adaptation is executed by a generic runtime system that uses these specifications which are referred to as Guiding Specifications. This has been demonstrated by way of a motivating real world example implemented on the .Net platform. It is shown how an adapter can be specified using a simplistic Guiding Specification and related XSLT documents. This allows the implementation to work more efficiently than hand coding each adapter. It is the underlying generic runtime support that provides much of this benefit. Component based software engineering (CBSE) constructs applications by assembling components together, CBSE has been of great help to application developers due to the very fact that tailor made components can be purchased from third party vendors and can be plugged-in to a system to form a working application. But in practice 'as-is' reuse is very unlikely to occur, and most components need to be changed in some way to match the requirements of the application architecture and other components. The process of changing thecomponent for use in a particular application is often referred to as Component Adaptation.

Abstract:

This Master thesis enhances an existing library search system with a new dynamic web interface and introduces the ability to perform remote searches by using Web Services. The remote search functionality also includes the ability to compress SOAP-messages, this functionality is optional. The system is implemented using the Microsoft.NET Framework with Visual Studio C#. A library needs to store information about articles and we have chosen to use a Sybase Adaptive Server Anywhere database.

The practical part of this thesis describes the architecture of our implementation and the design process.

The theoretical part is a comparative study between dynamically created web pages and static pages, SOAP-compression versus no compression, SOAP-optimization versus no optimisation and the use of Web Services locally versus local classes.

Abstract:
This thesis provides an overview of Web Services technology. The concept of Web Services and Service Oriented Architecture are explained. The thesis focuses on the mechanisms for transporting and addressing messages in web services, especially SOAP. It presents the development history of SOAP, an overview of the SOAP 1.2 specification, and the differences between SOAP in version 1.1 and 1.2. Further, the thesis presents two web servers for development and deployment of web services using Java and .NET technology, i.e. Bea Weblogic Server 9.2 and Internet Information Services 7.0. The web server implementations are evaluated both in terms of conformance to the SOAP specifications as well as their performance (response time and throughput). The results showed that the servers performed very similar both for SOAP 1.2 and SOAP 1.1 messages. The response times and throughput are similar for both servers in most cases. There are, however, situations when Weblogic perform significantly worse than IIS, and when IIS is noticeable worse than Weblogic. The thesis presents also general security aspects of sending messages.

Abstract:
The Internet became a standard way of exchanging business data between B2B and B2C applications and with this came the need for providing various services on the web instead of just static text and images. Web services are a new type of services offered via the web that aid in the creation of globally distributed applications. Web services are enhanced e-business applications that are easier to advertise and easier to discover on the Internet because of their flexibility and uniformity. In a real life scenario it is highly difficult to decide which J2EE application server to go for when deploying a enterprise web service. This thesis analyzes the various ways by which web services can be developed & deployed. Underlying protocols and crucial issues like EAI (enterprise application integration), asynchronous messaging, Registry tModel architecture etc have been considered in this research. This paper presents a report by analyzing what various J2EE application servers provide by doing a case study and by developing applications to test functionality.

A Engenharia de Software tem desenvolvido técnicas e métodos para apoiar o desenvolvimento de software confiável, flexível, com baixo custo de desenvolvimento e fácil manutenção. A avaliação da manutenibilidade contribui para fornecer meios para produzir software com alta qualidade. Este trabalho apresenta um experimento controlado para avaliar a manutenibilidade entre as abordagens de web services: RESTful e SOAP-WSDL. Esta avaliação foi conduzida usando 3 programas implementados na linguagem de programação Java e com a mesma arquitetura. Com base na arquitetura projetada, os web services desenvolvidos foram utilizados como objetos em estudos de caso, possibilitando avaliar e comparar a sua manutenibilidade. Os resultados obtidos demonstraram relações entre as informações sobre o custo e a qualidade dos serviços web, que contribuíram para esclarecer os critérios para a obtenção de uma boa relação entre o custo da manutenção e a evolução dos serviços web. Para concluir, os resultados indica que os web services RESTful são mais manuteníveis do lado do servidor, e os web services SOAP-WSDL são mais manuteníveis do lado do cliente. Os estudos realizados no experimento controlado são promissores e podem auxiliar na redução de custo na manutenção dos serviços web, melhorando dessa forma a qualidade do software no geral

This paper presents an controlled experiment to evaluate the maintainability between the approaches of web services: RESTful and SOAP-WSDL. This evaluation was conducted using four programs implemented in the Java programming language, using the same architecture. Based on the designed architecture, Web services were developed as objects used in case studies, allowing to evaluate and compare its maintainability. The results showed relationships between the information on the cost and quality of web services, which contributed to clarify the criteria for obtaining a good relationship between the cost of maintenance and evolution of web services. In conclusion, the results indicate the RESTful web services are more maintainable server side in contrast to the SOAP-WSDL web services are more maintainable client side. Studies in controlled experiments are promising and may help reduce the maintenance cost of web services, thus improving overall software quality

Abstract:
E-business innebär att företag använder Internetteknologier eller nätverksteknologier för att skapa större affärsnytta i deras affärsprocesser. För att kunna genomföra automatiserade affärsprocesser krävs att de olika system som används är interoperabla, d v s kan kommunicera och fungera ihop på ett effektivt sätt. Målet med Web Services är att skapa hög interoperabilitet, vilket gör denna teknik lämplig för e-business. Företag kan specialicera sig på att skapa specifika Web Services. Dessa Web Services kan sedan vara byggstenar åt andra företags tjänster. Det krävs då att Web Services kan integreras på ett bra sätt så att de verkligen bildar en affärsprocess. Därför är även frågor kring hur integration mellan Web Services ska gå till, viktigt ur ett e-bussiness perspektiv. Det vi kommit fram till är att det går att minimera integrationsproblemen genom att anvä nda de mest standardiserade protokollen och följa vissa riktlinjer vid skapandet av Web Services. Dessutom går det att testa interoperabiliteten på den skapade Web Servicen genom att använda olika testverktyg såsom XMLBus. Vi tror att Web Services är den definitiva tekniken för framtida e-business. Med den snabba utvecklingen som nu sker på området anser vi att det inte dröjer alltför lång tid innan företag kan få tilltro till tekniken och därmed börjar använda den. Förhoppningsvis skyndar överrenskommelser i form av kontrakt mellan kund och leverantör, s k Service Layer Agreements, på denna process.

Abstract:
Sistemas computacionais são constituídos por componentes de hardware e software que podem eventualmente falhar. Por esse motivo, o mecanismo de transação sempre foi imprescindível para a construção de sistemas robustos. O suporte transacional para a tecnologia Web services foi definido em agosto de 2005, num conjunto de três especificações denominadas WS-Coordination, WS-AtomicTransaction e WS-BusinessActivity. Juntas, essas especificações definem um alicerce sobre o qual aplicações robustas baseadas em Web services podem ser construídas. Nesta dissertação realizamos um estudo sobre transações atômicas em ambientes Web services. Em particular, estendemos o gerenciador de transações presente no servidor de aplicações JBoss, de modo que ele passasse a comportar transações distribuídas envolvendo Web services. Além disso, avaliamos o desempenho desse gerenciador de transações quando ele emprega cada um dos seguintes mecanismos de chamada remota: Web services/SOAP, CORBA/IIOP e JBoss Remoting. Finalmente, realizamos experimentos de escalabilidade e interoperabilidade.
Computing systems consist of a multitude of hardware and software components that may fail. For this reason, the transaction mechanism has always been essential for the development of robust systems. Transactional support for the Web services technology was defined in August 2005, in a set of three specifications, namely WS-Coordination, WS-AtomicTransaction, and WS-BusinessActivity. Together, such specifications enable the development of robust Web services applications. In this dissertation we studied atomic transactions in the Web services realm. Particularly, we added Web services atomic transaction support to the existing JBoss application server transaction manager. Furthermore, we evaluated the performance of this transaction manager when it employs each of the following remote method invocation mechanisms: Web services/SOAP, CORBA/IIOP and JBoss Remoting. Finally, we performed scalability and interoperability experiments.

Abstract:
Web Services have been the dominant technology in business integration and implementation of service oriented architectures. PHP is a server-side language popular for development of applications. A significant advantage of PHP is its light weight development for feature-rich web applications. Typically, PHP is used for making good-looking front end user interfaces; Java or other programming languages are used to develop the back end application. A secure and robust way for PHP programs to call back-end services is by Web Services. However, when the Web Service operations have complex interfaces, writing PHP client code can be difficult and error-prone. This thesis research seeks to develop a Web service-PHP program middleware that automatically handles the client-side Web Service calls. Two Web Services are developed, as well as two Web applications that consume the two Web Services, and experiments that demonstrate the usage of the WS-PHP middleware component are conducted.

Abstract:
Résumé : Les services Web, issus de l’avancée technologique dans le domaine des réseaux informatiques et des dispositifs de télécommunications portables et fixes, occupent une place primordiale dans la vie quotidienne des gens. La demande croissante sur des services Web multimédia (SWM), en particulier, augmente la charge sur les réseaux d’Internet, les fournisseurs de services et les serveurs Web. Cette charge est essentiellement due au fait que les SWM de haute qualité nécessitent des débits de transfert et des tailles de paquets importants. La qualité de service (par définition, telle que vue par l’utilisateur) est influencée par plusieurs facteurs de performance, comme le temps de traitement, le délai de propagation, le temps de réponse, la résolution d’images et l’efficacité de compression. Le travail décrit dans cette thèse est motivé par la demande continuellement croissante de nouveaux SWM et le besoin de maintenir et d’améliorer la qualité de ces services. Nous nous intéressons tout d’abord à la qualité de services (QdS) des SWM lorsqu’ils sont mis en œuvre sur des ordinateurs, tels que les ordinateurs de bureau ou les portables. Nous commençons par étudier les aspects de compatibilité afin d’obtenir des SWM fonctionnant de manière satisfaisante sur différentes plate-formes. Nous étudions ensuite la QdS des SWM lorsqu’ils sont mis en œuvre selon deux approches différentes, soit le protocole SOAP et le style RESTful. Nous étudions plus particulièrement le taux de compression qui est un des facteurs influençant la QdS. Après avoir considéré sous différents angles les SWM avec mise en œuvre sur des ordinateurs, nous nous intéressons à la QdS des SWM lorsqu’ils sont mis en œuvre sur FPGA. Nous effectuons alors une étude et une mise en œuvre qui permet d’identifier les avantages à mettre en œuvre des SWM sur FPGA. Les contributions se définissent en cinq volets comme suit : 1. Nous introduisons des méthodes de création, c’est-à-dire conception et mise en œuvre, de SWM sur des plate-formes logicielles hétérogènes dans différents environnements tels que Windows, OS X et Solaris. Un objectif que nous visons est de proposer une approche permettant d’ajouter de nouveaux SWM tout en garantissant la compatibilité entre les plate-formes, dans le sens où nous identifions les options nous permettant d’offrir un ensemble riche et varié de SWM pouvant fonctionner sur les différentes plate-formes. 2. Nous identifions une liste de paramètres pertinents influençant la QdS des SWM mis en œuvre selon le protocole SOAP et selon le style REST. 3. Nous développons un environnement d’analyse pour quantifier les impacts de chaque paramètre identifié sur la QdS de SWM. Pour cela, nous considérons les SWM mis en œuvre selon le protocole SOAP et aussi selon style REST. Les QdS obtenues avec SOAP et REST sont comparées objectivement. Pour faciliter la comparaison, la même gamme d’images (dans l’analyse de SWM SOAP) a été réutilisée et les mêmes plate-formes logicielles. 4. Nous développons une procédure d’analyse qui permet de déterminer une corrélation entre la dimension d’une image et le taux de compression adéquat. Les résultats obtenus confirment cette contribution propre à cette thèse qui confirme que le taux de compression peut être optimisé lorsque les dimensions de l’image ont la propriété suivante : le rapport entre la longueur et la largeur est égal au nombre d’or connu dans la nature. Trois libraires ont été utilisées à savoir JPEG, JPEG2000 et DjVu. 5. Dans un volet complémentaire aux quatre volets précédents, qui concernent les SWM sur ordinateurs, nous étudions ainsi la conception et la mise en œuvre de SWM sur FPGA. Nous justifions l’option de FPGA en identifiant ses avantages par rapport à deux autres options : ordinateurs et ASICs. Afin de confirmer plusieurs avantages identifiés, un SWM de QdS élevée et de haute performance est créé sur FPGA, en utilisant des outils de conception gratuits, du code ouvert (open-source) et une méthode fondée uniquement sur HDL. Notre approche facilitera l’ajout d’autres modules de gestions et d’orchestration de SWM. 6. La mise à jour et l’adaptation du code open-source et de la documentation du module Ethernet IP Core pour la communication entre le FPGA et le port Ethernet sur la carte Nexys3. Ceci a pour effet de faciliter la mise en œuvre de SWM sur la carte Nexys3. // Abstract : Web services, which are the outcome of the technological advancements in IT networks and hand-held mobile devices for telecommunications, occupy an important role in our daily life. The increasing demand on multimedia Web services (MWS), in particular, augments the load on the Internet, on service providers and Web servers. This load is mainly due to the fact that the high-quality multimedia Web services necessitate high data transfer rates and considerable payload sizes. The quality of service (QoS, by definition as it is perceived by the user) is influenced by several factors, such as processing time, propagation delay, response time, image resolution and compression efficacy. The research work in this thesis is motivated by the persistent demand on new MWS, and the need to maintain and improve the QoS. Firstly, we focus on the QoS of MWS when they are implemented on desktop and laptop computers. We start with studying the compatibility aspects in order to obtain MWS functioning satisfactorily on different platforms. Secondly, we study the QoS for MWS implemented according to the SOAP protocol and the RESTful style. In particular, we study the compression rate, which is one of the pertinent factors influencing the QoS. Thirdly, after the study of MWS when implemented on computers, we proceed with the study of QoS of MWS when implemented on hardware, in particular on FPGAs. We achieved thus comprehensive study and implementations that show and compare the advantages of MWS on FPGAs. The contributions of this thesis can be resumed as follows: 1. We introduce methods of design and implementation of MWS on heterogeneous platforms, such as Windows, OS X and Solaris. One of our objectives is to propose an approach that facilitates the integration of new MWS while assuring the compatibility amongst involved platforms. This means that we identify the options that enable offering a set of rich and various MWS that can run on different platforms. 2. We determine a list of relevant parameters that influence the QoS of MWS. 3. We build an analysis environment that quantifies the impact of each parameter on the QoS of MWS implemented on both SOAP protocol and RESTful style. Both QoS for SOAP and REST are objectively compared. The analysis has been held on a large scale of different images, which produces a realistic point of view describing the behaviour of real MWS. 4. We develop an analysis procedure to determine the correlation between the aspect ratio of an image and its compression ratio. Our results confirm that the compression ratio can be improved and optimised when the aspect ratio of iiiiv an image is close to the golden ratio, which exists in nature. Three libraries of compression schemes have been used, namely: JPEG, JPEG2000 and DjVu. 5. Complementary to the four contributions mentioned above, which concern the MWS on computers, we study also the design and implementation of MWS on FPGA. This is justified by the numerous advantages that are offered by FPGAs, compared to the other technologies such as computers and ASICs. In order to highlight the advantages of implementing MWS on FPGA, we developed on FPGA a MWS of high performance and high level of QoS. To achieve our goal, we utilised freely available design utilities, open-source code and a method based only on HDL. This approach is adequate for future extensions and add-on modules for MWS orchestration.

Resumo: A gerência de redes é formada por cinco áreas funcionais: Falha, Configuração, Contabilidade, Desempenho e Segurança. A área de configuração é responsável pela operação e manutenção da rede, acompanhando as mudanças de configuração realizadas em cada dispositivo da rede. As principais ferramentas de gerência disponíveis, CLI e SNMP, não atendem aos requisitos de configurações das redes atuais. Novas tecnologias Web estão se tornando comuns na gerência de redes, com destaque para o uso da linguagem XML e do protocolo HTTP. Com o objetivo de aplicar estas novas tecnologias na configuração de redes foi definido, no âmbito do IETF, um novo protocolo de gerência de configuração denominado NETCONF. Este trabalho faz um estudo do protocolo NETCONF procurando destacar as suas vantagens e limitações. Este trabalho propõe, também, uma arquitetura de implementação para o NETCONF baseada no protocolo de transporte SOAP sobre HTTP, ou sobre HTTPs. Com o objetivo de validar a arquitetura, apresentamos a implementação de um protótipo totalmente aderente à proposta NETCONF para o qual foi especificado um modelo de dados para configuração de VLANs de switches de fabricantes diferentes
Abstract: Network management is formed by five functional areas: Failure, Configuration, Accounting, Performance and Security. The configuration area is responsible for the network¿s operation and maintenance, following the configuration changes done in each network¿s device. The main management tools available, CLI and SNMP, do not take care of the configuration requirements of current networks. New Web technologies are becoming widespread in network management, with prominence of XML language and HTTP protocol. A new protocol of configuration management named NETCONF has been defined, in the scope of the IETF, in order to apply these new technologies for configuration of networks. This work studies the NETCONF protocol aiming to highlight its advantages and limitations. This work also proposes an architecture of implementation for the NETCONF based on the transport protocol SOAP over HTTP, or HTTPs. Aiming to validate such architecture, we present the implementation of a prototype fully adherent to the NETCONF proposal, for which it has specified a model of data for configuration of VLANs of switches from different manufacturers

Abstract:
One of the most crucial decisions when developing a system based on Service Oriented Architecture is to select an appropriate server which will be the ground for building the application. Similar to databases, an application server has significant influence on efficiency, stability, and security of entire system. During the preparation of architecture for system development one has to decide which available application server would be optimal for hosting and maintaining v Web Services in the given case. There are multiple significant criteria that lead to the proper choice. The impact on a decision among other things is type of the physical machine on which the application server is installed, estimated number of simultaneous clients, and sizes of requests and responses between clients and server. The goal for this thesis is to conduct the comparative analysis of the most commonly used application servers using Service Oriented Architecture and to determine which server should be applied in which particular cases. Performance and load tests will be conducted using SoapUI application.

Abstract:

This thesis describes the development of a SOA-based architecture for integrating large EDI-using manufacturing companies purchasing processes with smaller non-EDI capable manufacturing companies, using online services.

The underlying need for this project lies with the fact that these small manufacturing companies risk to miss out on business, due to their inability to communicate via the industry standard EDI format. At the same time, getting EDI-capable involves significant investments in software licenses, connectivity services and consulting or training that these small companies may not be ready to make. The mentor company of this thesis project, System Andersson, produces resource planning software for this type of companies and would like to be able to provide them with an easy to use way of “jacking in” EDI support into their businesses, without having to make such significant investments. Ideally this feature would be developed as a standalone subscription based service that could be provided to users in such a way that their existing System Andersson software could connect to it and no further hard- or software would be needed on site. This EDI-enabling should be as easy as to be entirely transparent for the end-user companies. The task handed to the author was thus to develop an architecture for how such a subscription based service could be developed. Furthermore, in order to promote re-use and simplify development, the architecture was to be based on SOA concepts.

As a result of the project, such an architecture has been developed. The architecture details two services for translating and storing for later delivery a number of EDI message types of the EDIFACT variety. The architecture also specifies communications protocols (SOAP over HTTPS and AS2 over HTTPS) and APIs (web services) for how to communicate with these services. These specifications can be used to implement a system that performs the necessary integration, so that the smaller companies may indeed communicate via EDI.

The fitness of the developed architecture has been tested by implementing a prototype version of such a system based on it. It has also been validated by way of comparing to how well it adheres to SOA design principles. All in all, this design appears to be quite sound and presents a working solution to the studied problem.

The control of industrial processes has become increasingly complex due to variety of factory devices, quality requirement and market competition. Such complexity requires a large amount of data to be treated by the three levels of process control: field devices, control systems and management softwares. To use data effectively in each one of these levels is extremely important to industry. Many of today s industrial computer systems consist of distributed software systems written in a wide variety of programming languages and developed for specific platforms, so, even more companies apply a significant investment to maintain or even re-write their systems for different platforms. Furthermore, it is rare that a software system works in complete isolation. In industrial automation is common that, software had to interact with other systems on different machines and even written in different languages. Thus, interoperability is not just a long-term challenge, but also a current context requirement of industrial software production. This work aims to propose a middleware solution for communication over web service and presents an user case applying the solution developed to an integrated system for industrial data capture , allowing such data to be available simplified and platformindependent across the network

Abstract:
Current global business competition has resulted in significant challenges for manufacturing and production sectors focused on shorter product lifecyc1es, more diverse and customized products as well as cost pressures from competitors and customers. To remain competitive, manufacturers, particularly in automotive industry, require the next generation of manufacturing paradigms supporting flexible and reconfigurable production systems that allow quick system changeovers for various types of products. In addition, closer integration of shop floor and business systems is required as indicated by the research efforts in investigating "Agile and Collaborative Manufacturing Systems" in supporting the production unit throughout the manufacturing lifecycles. The integration of a business enterprise with its shop-floor and lifecycle supply partners is currently only achieved through complex proprietary solutions due to differences in technology, particularly between automation and business systems. The situation is further complicated by the diverse types of automation control devices employed. Recently, the emerging technology of Service Oriented Architecture's (SOA's) and Web Services (WS) has been demonstrated and proved successful in linking business applications. The adoption of this Web Services approach at the automation level, that would enable a seamless integration of business enterprise and a shop-floor system, is an active research topic within the automotive domain. If successful, reconfigurable automation systems formed by a network of collaborative autonomous and open control platform in distributed, loosely coupled manufacturing environment can be realized through a unifying platform of WS interfaces for devices communication. The adoption of SOA- Web Services on embedded automation devices can be achieved employing Device Profile for Web Services (DPWS) protocols which encapsulate device control functionality as provided services (e.g. device I/O operation, device state notification, device discovery) and business application interfaces into physical control components of machining automation. This novel approach supports the possibility of integrating pervasive enterprise applications through unifying Web Services interfaces and neutral Simple Object Access Protocol (SOAP) message communication between control systems and business applications over standard Ethernet-Local Area Networks (LAN's). In addition, the re-configurability of the automation system is enhanced via the utilisation of Web Services throughout an automated control, build, installation, test, maintenance and reuse system lifecycle via device self-discovery provided by the DPWS protocol.

Abstract:
Today, Peer-to-peer (P2P) computing and Web Services play an important role in networking and computing. P2P computing, that aims addressing all the resources in a network and sharing them, is an old paradigm that gains importance nowadays with the advent of popular file sharing and instant messaging applications. On the other hand, a Web service is a software system that has an interface allowing applications to interact with other applications through Internet or intranet. Providing methods for publishing and discovering Web services from which mobile devices can facilitate in a P2P environment enables exploitation of P2P and Web service technologies efficiently by mobile devices. This also extends the range of devices that facilitate P2P and Web services technologies from servers and desktop computers to personal digital assistants (PDAs) and mobile phones. In this thesis, an architecture that enables publishing and discovering Web services for mobile clients that are inter-connected in a P2P environment is introduced. Key issues in this architecture are allowing mobile devices to join in a P2P network group, publishing Web services and discovering these services in P2P network. Invoking Web services that are published and discovered is another key issue in this architecture. The architecture introduced exploits P2P and Web services standards using various tools for mobile devices. For the purpose of organizing a P2P environment, JXTA protocols and services are used. WSDL is used for describing Web services. JXTA advertisements help in publication and discovery of Web services
and BPEL enables composition, deployment and execution of Web services. The architecture introduced within the scope of this thesis combines all these standards with tools that enable use of these standards on mobile devices. The work done in this thesis is realized as a part of Artemis, a project funded by European Commission for providing interoperability of medical information systems.

Abstract:
När fler och fler väljer att lära sig programmering kan det vara bra att öva på attlösa problem, genom att skriva funktioner som sedan kan testas för att se omanvändaren har lyckats. Function Practice är en tjänst för att kunna öva programmeringpå just detta sätt, genom att lösa uppgifter med att skriva funktioneri olika programmeringsspråk, de språk som kommer kunna användas ärJava, C++ och Python. Det ger även ett lätt och smidigt sätt att skapa sådanauppgifter. Syftet med projektet är att utveckla denna tjänst, genom att skapa enwebbtjänst som kan kompilera och köra funktioner för de olika språken, enhemsida som användarna kan skriva och testa kod på, samt ett sätt att definierauppgifterna som ska lösas, detta testas sedan med hjälp av ett användartest i enmindre grupp för att se om hur användarvänlig den är, samt att funktionalitetentestas och jämförs med några tidigare lösningar. Tjänsten testas för att se om ytterligaresäkerhet behövs genom att försöka att köra kommandon på värdsystemet.Slutsatsen av projektet är funktionaliteten bakom tjänsten fungerar dock atthemsidan behöver vara lite tydligare för att den ska vara mer användarvänlig,samt att användaren borde kunna få felmeddelanden utifall något inte fungerarför att de lättare ska veta vad de behöver göra. Säkerheten visar sig vara en viktigdel då det går att köra kommandon på värdsystemet vilket ger användarnafull kontroll på systemet.
As more and more people choose to learn programming it may be good to practicesolving problems by writing functions that can then be tested to see if theuser has succeeded. Function Practice is a service to be able to practice programmingin exactly this way, by solving tasks of writing functions in differentprogramming languages, the languages that will be used is Java, C ++ andPython. It also provides an easy and convenient way to create such tasks. Theaim of the project is to develop this service by creating a Web service that cancompile and run functions for the different languages, a website that users canwrite and test code, as well as a way to define the tasks to be solved, this is thentested with a user test in a smaller group to see how user-friendly it is, and thefunctionality is tested and compared with some previous solutions. The serviceis tested to see if additional security is needed by trying to run commands onthe host system. The conclusion of the project is that the functionality behindthe service works, however, that the website needs to be a little clearer for it tobe more user-friendly, and that the user should be able to get error messages incase something does not work to make it easier to know what they need to do.Security proves to be an important part when it is possible to execute commandson the host system which gives users full control of the system.

This paper presents a proposal for architecture for interconnection of wireless sensor networks and the Internet using only the application layer, without the need to change the protocol stack of both networks. The architecture is based on the HTTP protocol, proposing the use of web services technology to interconnect the two network standards. From the installation of a wireless sensor network in a closed environment, its interconnection was performed with the Internet based on the proposed architecture using open standard technologies, the protocol for REST web services and cloud computing structure of the company Amazon Web Services. Information was collected to evaluate the functionality, reliability and system efficiency, accordingly to the ABNT standard, ISO / IEC 9126. The results showed the feasibility of implementing this proposal because it was shown that the interconnection is possible between these network standards using the application layer, reliably, efficiently and with the use of low cost resources. This study might encourage proposals to extend the accessibility of sensor networks to mobile devices.

Abstract:
Present web is aiming to the possibility of automatization of user behavior on web applications. Adding of semantics and creation of web service interface are the main approaches for accomplishment of this user comfort. Nevertheless, this direction brings some problems which can make more difficult publishing and implementation of web documents. Web services can connect heterogeneous systems, because they are based on XML markup language that is a place where all applications can meet without lost of platform independence. The automatic transformation of a web application into a web service could be considerably more effective than to create a web service from the beginning. However, this step is for some applications almost unreal without knowledge of their inner structure. In most cases, the transformation will be done semiautomatically with help of human decisions.

Abstract:
In the African continent the mobile phones are already contributing theirshare in the development of the continent. Specially in Ethiopia, in onedirection, the users of mobile phones are increasing each year and mostimportantly the small scale farmers who contribute 85% of the country’spopulation are using these devices to trade their surplus products in anefficient manner and better deal thus earn good profit. In anotherdirection, Ethiopia has set up its own Commodity Exchange in 2008 sothat farmers and traders could buy and sell commodities in an efficientand transparent manner. Taking into consideration both of thesedevelopments carried out to encourage smooth trade and modernmarking strategies, this project has a target to come up with mobileapplications for the Android mobile platform and iPhone users in the firstphase of implementation. Accordingly, the app developed will help to getreal time Ethiopia commodity Exchange (ECX) market prices, commodityrelated headlines, weather forecasts and other relevant news. It willcontribute to standardize the way ECX is performing to link up differentparties specially farmers who make up majority of the country’spopulation and support the economy of the country in a great deal withthe traders. Although the mobile app developed does not have an aim tobring in significant change into the existing system at the currentpenetration of Smartphone in the country, it helps to disseminateinformation in standardized manner as in big commodity exchanges andbesides, we believe in the future it will be the convenient and widely usedmeans to reach the traders with necessary information.

Abstract:
Basés sur les protocoles XML, SOAP et WSDL, les Services Web (SW) sont la technologie de base pour le développement d'Architectures Orientées Services (AOS). Ces architectures permettent de mettre en place des applications faiblement couplées avec un fort degré de configuration dynamique. Elles se basent sur la notion de relation de "services" formalisée par un contrat qui unit le client et le prestataire de services. Ce contrat est le point charnière de ce type d'applications. D'un point de vue purement marketing, les Services Web peuvent être développés pour satisfaire les besoins des clients, être facile à maintenir et aussi fournir un haut niveau de qualité de service. Les prestataires de Services Web doivent s'assurer de la fiabilité et de la disponibilité de leur infrastructure individuelle de Services Web. Cependant, les prestataires ne peuvent pas tenir compte de tous les besoins possibles des clients et des contraintes liées au développement de l'application donnée. Cela signifie que des mécanismes additionnels doivent être développés et ciblés pour un contexte d'utilisation donné. C'est exactement le type de problèmes que j'ai examiné dans mes travaux. Les développeurs d'application regardent les Services Web comme des COTS (Component Off-The Shell) et ignorent donc leurs implémentations et leurs comportements en présence de fautes. De ce point de vue, les clients ont besoin de développer des mécanismes de tolérances aux fautes spécifiques bien adaptés à leurs applications. Dans ce but, mes travaux de thèse m'ont conduit à proposer une plate-forme pour aider les clients à réaliser des connecteurs spécifiques de tolérance aux fautes (SFTC - Specifique Fault Tolerance Connectors) qui implémentent des filtres et autres techniques de détection d'erreurs (c.à.d des assertions exécutables) ainsi que des mécanismes de recouvrement qui sont déclenchés quand les Services Web ne satisfont plus les caractéristiques de sûreté demandées. De plus, le même Services Web peut être employé dans plusieurs applications orientées services avec différentes contraintes et peut donc tirer profit de plusieurs connecteurs (SFTCs). Le problème est similaire à l'utilisation des composants COTS dans les systèmes critiques de sûreté, et des travaux précédents ont déjà prouvé que des mécanismes tels que les wrappers étaient une solution possible. La différence dans le contexte des Architectures Orientées Services est que des wrappers prédéfinis ne peuvent pas être spécifiés pour satisfaire tous les besoins possibles. L'approche doit être plus adaptative pour permettre à des mécanismes de sûreté : 1) d'être définis au cas par cas pour une utilisation donnée du Service Web et 2) d'avoir une forte dynamique afin d'être modifiés selon les besoins. Ainsi, mes travaux de recherches ont permis de fournir aux développeurs d'Architectures Orientées Services: 1) un langage nommé DeWeL pour décrire les caractéristiques de sûreté de fonctionnement du connecteur et 2) l'infrastructure IWSD pour dynamiquement contrôler et exécuter les connecteurs dans des applications critiques. L'objectif final est de fournir aux développeurs d' Architectures Orientées Services une infrastructure et des outils capables de les aider à déployer des applications orientées services tolérants les fautes.

Abstract:
This thesis focuses on design of document exchange solution used between Stavební spořitelna České spořitelny a.s. (SSČS) and its external sales network, which is outdated and doesn't meet the needs of SSČS or sales network. The thesis also includes the identification of suitable basic principles used in the service-oriented architecture (SOA) concept and their application in design solutions. The aim of the thesis is a conceptual solution design, based on the principles of SOA and the following technological design of changes in existing environment, so that on this basis could be created a functional and technical specification for suppliers of these applications. Stated objective is achieved through an initial analysis of the current environment, which identifies the possibilities of existing applications, and identifies weaknesses in the process that will be changed in the new solution. The analysis covers as the environment of external sales network as the related environment in SSČS, which together figure in the process of documentation exchange. As the results of the analysis and based on theoretical knowledge and consultation with experts in the field of SOA is then formulated a proposed solution at the conceptual level, which is further elaborated in the description of the proposed changes in individual components of the new solution. The outputs of this thesis will serve SSČS both in terms of describing the existing and the new environment, and as an input for the specifications of the proposed amendments to the supplier concerned applications. Structure of the thesis consists of introduction, devoted to the characterization of SSČS and providing an initial framework for solved domain. This is followed by a description and the analysis of external sales network, particularly in terms of application equipment and communication flows, followed by a description of the environment in SSČS, which contains the components processing sent documents. Next part of thesis is devoted to the formulation of the basic concepts of SOA and selection of appropriate principles that are followed in the subsequent section to draft the solution itself, first at the conceptual level, followed by a detailed description of the necessary changes. Everything is then evaluated in the final part.

Abstract:
Traditional architectures of software systems are in heterogenous environment of today's computer networks too heavy-footed. One of principles, which tries to solve this problem is service-oriented architecture (SOA). Practical way of its implementation is represented by web services (WS) built upon protocols like SOAP or XML-RPC. This diploma thesis focuses problem of providing contextual information to mobile devices and its solution based on SOA principles. The thesis introduces design and implementation of web service providing contextual information to mobile devices and prototype of modular inverse SOAP proxy server allowing its effective monitoring and management.

Abstract:

Detta examensarbete behandlar Service Oriented Architecture (SOA) och dess implementeringar Jini och Web services. SOA beskriver hur applikationsintegration mellan olika plattformar skall ske och innebär att applikationer designas som tjänster för att enkelt integreras med andra applikationer. Dynamisk lokalisering av tjänster via en registertjänst används för att applikationer skall finna andra applikationer. Vi designar och implementerar en mekanism i Web services som gör det möjligt att byta en tjänst under exekvering. Ett sådant byte kan vara intressant av två skäl, tjänster kan registreras utan att vara tillgängliga, eller att det uppstår ett fel under exekvering som gör att tjänsten blir otillgänglig.


This degree project is about Service Oriented Architecture (SOA) and its implementations Jini and Web services. SOA is a description of how application integration between different platforms can be carried out by designing applications as services, which implies an easier integration with other applications. Dynamic location of services is carried out by consultation with a register service so that applications can find other applications. We design and implement a mechanism in Web services that makes it possible to change service during execution. A change of service can be interesting for two reasons, the service might be registered but not available or there might be some sort of fault during execution that makes the service unavailable.

Abstract:
It is desirable that SOAP performs efficiently in environments where there are a large number of transactions. However, SOAP is based on XML and therefore inherits XML's disadvantage of having voluminous messages. Firstly, the performance of different SOAP bindings is investigated. A benchmark of different SOAP bindings in wireless environments demonstrates the unsuitability of HTTP and TCP bindings in limited bandwidth environments. UDP is recommended as an alternative transport protocol for SOAP. Secondly, the thesis examines the use of multicast in reducing the traffic caused by SOAP messages in low bandwidth environments to deal with challenges described. A novel SOAP-level multicast protocol based on the similarity of SOAP messages, called SMP (Similarity-based SOAP Multicast Protocol), is proposed. In particular, issues of traffic, network optimization, response time and scalability are investigated. Lastly, two extensions of SMP are proposed to further improve the performance of SMP. SMP's extensions are two algorithms, greedy and incremental tc-SMP, for traffic-constrained similarity-based SOAP multicast. Tc-SMP optimizes network traffic by building its own spanning trees instead of using the one built by traditional methods, such as Dijkstra's algorithm. A new client is added to a tc-SMP tree through an existing tc-SMP node that causes minimal additional traffic for that connection. Detailed analytical models and experimental evaluations of the proposed methods demonstrate that combining SOAP messages of similar content and multicasting them as aggregated messages can significantly lower total network traffic. These improvements are advantageous for Web service applications that involve a high number of simultaneous similar transactions such as stock quotes, weather and sport event reports.

Abstract:
A velocidade das mudanças e a necessidade de informações disponíveis em vários meios têm feito com que os sistemas atuais se integrem cada vez mais. Neste cenário, arquiteturas orientadas a serviços e Web Services ganham evidência. Por utilizarem padrões já bem difundidos, por exemplo XML (extended markup language), Web Services se destacam pela interoperabilidade e dinamismo, disponibilizados através da Internet e utilizado em ambientes heterogêneos. Contudo, isso afeta significativamente atributos não funcionais, por exemplo, confiabilidade, disponibilidade, entre outros. Para Web Services, além de todos os problemas existentes no paradigma de programação distribuída, temos ainda o problema de que erros em um determinado serviço não devem ser propagados para os demais. Dentre as diversas formas de se contornar o problema, existe a definição de padrões transacionais que visam delinear regras específicas para a comunicação entre os serviços. O objetivo do trabalho é identificar casos de testes que permitam validar a adequação, tanto do serviço quanto da aplicação de padrões definidos, de modo a garantir uma maior confiabilidade do sistema como um todo. Para isso, é avaliada a aplicabilidade de técnicas de perturbação e mutação de dados com relação ao padrão estabelecido. Como resultado, obtém-se um subconjunto das técnicas que possuem potencial de identificação de falhas nesse cenário.
Software technology has become essential since it is available in most places. Powered by Internet, nowadays, information quickly flows throw systems. Web Services provide a standard way to meet these objectives, as they use common communication pattern like XML and HTTP. The use of Web Services brings many benefits. On the other hand, it also brings some issues about reliability, availability and other non functional problems. Transactional patterns are an alternative to outline such problems. This study aims to find an effective way to certificate the correct use of those patterns by applying perturbation and mutation testing techniques. As work result, it is expected to determine which of techniques are applicable.

Abstract:
Service-Oriented Architecture (SOA) represents an emerging architectural approach that is able to tackle challenges in the contemporary service-based economy, in which the global market revenues are shifting from the manufacture of traditional off-the-shelf products to the provision of diversified services that suffice for customers’ needs. In such a service-based economy, one can envisage an entirely “service-oriented” world, where a massive number of distributed services with different natures and capabilities are provided by various professionals around the world. Problems arise when business applications demand desirable services through different sources and providers that are appropriate for their own benefits and preferences. Therefore, it can be very challenging to design an SOA infrastructure that enables users to exploit this great level of service heterogeneity and quantity. One of the key issues in service-oriented architecture is to achieve efficient service discovery and loosely-coupled service distribution while maintaining a satisfactory degree of scalability, usability, and Web consistency. This thesis deals with SOA infrastructure-level design and implementation issues. It approaches this SOA infrastructure within the scope of Web services, which capture an important, and perhaps the best, ‘realisation’ of SOA. It investigates and formulates how public Web services distributed across the World Wide Web can be augmented by a software platform that enables scalable, user-centred,semantic-enabled, and integration-oriented service retrieval, selection, and matching. The primary goal of this thesis is thus to propose a conceptual framework of an enhanced SOA infrastructure with regard to service distribution and discovery.
It also aims to design and implement a platform (PWSP), by means of which a large number of public Web services on the Web can be distributed based on service demands, retrieved based on service descriptions, selected based on service qualities, and matched based on service messages in a user-centred, scalable, and Web-consistent manner without augmenting existing Web services standards.

Full text
Abstract:

Denna studie undersöker om, och isåfall hur, nätverksfördröjningar uppstår då små SOAP-meddelanden skickas över TCP/IP. För att utföra detta skapades ett litet nätverk och i det genomfördes mätning av svarstider för två olika SOAP-implementationer, Apache SOAP och Microsoft SOAP Toolkit. Resultaten från mätningarna analyserades och visade att det uppstår nätverksfördröjningar då små SOAP-meddelanden skickas över TCP/IP. Både Apache SOAP och Microsoft SOAP Toolkit uppvisade olika strategier i nätverkskommunikationen vilket påverkade svarstider. För Apache SOAP uppstod fördröjningar vid varje SOAP-anrop, oberoende av storleken på meddelandet som returnerades, medan Microsoft SOAP Toolkit undvek nätverksfördröjningar då meddelandet som returnerades var tillräckligt stort.

Abstract:
Web Services is one of the latest golden concepts that promise flexibility and unlimited potential for interconnection between systems of the same or different type. The communication is based on SOAP ? Simple Object Access Protocol, which is founded on XML (eXtended Markup Language). We have made experiments with SOAP in a Web Service Environment to find out the performance in response time using SOAP compared to CORBA. Unsurprisingly CORBA (Common Object Request Broker Architecture) is significantly faster but with the improvements that we implemented and an intelligent choice of XML parser the response times for SOAP was drastically lowered.

Abstract:
This Master’s Thesis examines and documents challenges related to the flexible interchange of web services within a cross-cloud Service Oriented Computing scenario (SOC).Starting with a theoretical approach, hypotheses are defined and processed to create testing scenarios for a practical examination. Both examinations are used to identify possible challenges. Next, encountered challenges are described, discussed and classified. Lastly, solution approaches to identified challenges are presented. The solution approaches concern related topics, such as service standardization, semantic methods, heuristics, and security/trust mechanisms. Several approaches to different challenges are reviewed in this particular context, to present an overview for future research on the subject.It is remarkable that there will be more service standardization in the future, but to achieve full automation it will be, on the long run, necessary to evolve and adopt more sophisticated solution approaches such as semantic methods or heuristics.This work is embedded into the framework of a research co-operation between the Linnaeus University Växjö and the University of Applied Sciences Karlsruhe. Results however are also applicable to other research scenarios.
