Workshop Mensch-Computer-Vernetzung Übersicht über die technischen Grundlagen von Web Services Abgrenzung zu anderen RPC-Mechanismen Beispiele für Beschreibungssprachen

The diploma thesis describes the analysis, specification, origin and transformation of the current editing system N.E.S.P.I, which is the intellectual property of the company WebRex s.r.o. The main aim is to separate the administration of the web sites from their content, which can be seen on the Internet and by doing so to achieve the unified and complex administration interface for the customers. By bringing the service into work we do not only save time and simplify the work of the programmers, but we are also able to reach the stage when the editing system is not only the intellectual property of the company, but also its physical property, because the customer owns only the web sites, but the possibility to administrative them is offered as further service. The service should also provide the customers with modern access to informational technologies and propose enhanced assistance for their entrepreneurial plans and ideals.

近十年內網際網路迅速興起並蓬勃發展，對我們生活的各個層面造成劇烈的影響，並掀起電子商務的熱潮。目前最引人注目的焦點是B2B，利用網路的特性來降低成本，縮短供應鏈，加速產品生命週期。產業已注意到協同商務中之供應網絡管理，並探討企業問之商務管理所需之方法與資訊技術，以尋求新的企業營運模式。在相關發展中，WWW上之商務資料交換，更是目前發展之重點，我們的終極目標是一個跨產業且進入門檻小的全球性交易平台，ebXML因其可能帶來跨產業協同商務之平台架構逐成為產業矚目之對象。 另一個網路所帶來的問題是資訊爆炸。當人們才剛開始享受網路世界的多采多姿，馬上卻又得面臨資訊氾濫的夢魘。如何利用智慧型的方法，提昇搜尋的效率與提高資訊的效果，是我們所關心的。搜尋引擎的演算法發展已到極致，但在搜尋策略的輔助上仍有發展的空間。 本研究回顧電子商務的緣由與發展，提出web service輿ebMXL應用的跨產業網路交易平台，並設計以5W1H的方式儲存專家經驗與策略，透過查詢擴充的機制，達成搜尋策略與結果的改善，並在這個電子商務架構平台的註冊機制與儲存庫(registry/repository)上運作，讓代理人理解企業之需求與期望，進而完成企業間交易夥伴的尋找，以達成動態供應鏈之實現。 關鍵字：XML，ebXML，web service，UDDI，註冊機制與儲存庫，資訊檢索，搜尋策略，5W1H，後設資料 / Starting from the concept of B2B e-commerce in general, the aim of this thesis is to propose and test a method for supporting trading partners' matching, in particulars those who follows ebXML. In the first place, this research presents a study of the areas where XML may have significant contributions. To avoid falling into pitfalls that works in e-commerce have experienced, we ought to understand the evolution of e-commerce so that the target supports can be derived from learned lessons. With these caveats in mind, the next step is to clarify the characteristics and requirements of a generic B2B framework. Base on the aforementioned survey, the framework of ebXML can be clarified, which is considered as the State-of-Art e-business technology. To reach this, this research is to address not only the problem domain and original concepts but also technology requirements. The ebXML architecture as well as relevant initiatives, viz. SOAP, WSDL and UDDI are then examined to search for potential ebXML-based solutions. In a comparison to RosettaNet, ebXML can provide more efficient and effective searches and matches of trading partners on electronic market place. Among others, the author emphasizes the research into a hybrid of ebXML and so-called web based service technologies. To realize this concept, a searching and matching mechanism with aids of expert's strategies based on 5WIH knowledge schema is carried out in this research. Last but not least, 5W1H knowledge schema is applied, another word serves as metadata, to organize and store expert's heuristic and intelligence in so-called strategy base, so that this work can use the expert's strategy for expanding the keywords to refine user queries in the run-time and thus provide a more efficient and effective matching results. Keyword: XML, ebXML, web service, UDDI, registry/repository, information retrieval, searching strategy, 5W1H, metadata

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.

Background: With Web service growing popularity more and more companies chose to apply Web service in their organisation. With the rising usage of the concept the demands rise with it. For companies that deal with vulnerable information for example hospitals, there needs to be strong security measures taken. Purpose: The aim of the report is to examine different security functions that can help developers to secure Web service applications. The report will be written so that organisations such as health care organisation can get insight on how to use a secure Web services in their line of work. Method: One of the main methods used in this report is a qualitative hermeneutic way of thinking. The research process will apply Wallace’s model. The theoretical study is achieved with research on the subject through literature studies and published articles. Interviews that are used to gain knowledge are structured as quality orientated science surveys with semistandardised questions. Conclusions: We believe the time has come for hospitals to investigate if Web service can help their organization. In case they choose to use Web services, we advise them to follow Web service Security’s recommendations to produce a web service that is adapted to their security needs.

<p>It is not easy to apply XML in e-commerce development for achieving interoperability in heterogeneous environments. One of the reasons is a multitude of XML-based Frameworks for Internet Commerce (XFIC), or industrial standards. This thesis surveys 15 frameworks, i.e., ebXML, eCo Framework, UDDI, SOAP, BizTalk, cXML, ICE, Open Applications Group, RosettaNet, Wf-XML, OFX, VoiceXML, RDF, WSDL and xCBL.</p><p>This thesis provides three models to systematically understand how the 15 frameworks meet the requirements of e-commerce. A hierarchical model is presented to show the purpose and focus of various XFIC initiatives. A relationship model is given to show the cooperative and competitive relationships between XFIC. A chronological model is provided to look at the development of XFIC. In addition, the thesis offers guidelines for how to apply XFIC in an e-commerce development.</p><p>We have also implemented a B2B e-procurement system. That not only demonstrates the feasibility of opensource or freeware, but also validates the complementary roles of XML and Java: XML is for describing contents and Java is for automating XML documents (session handling). Auction-based dynamic pricing is also realized as a feature of interest. Moreover, the implementation shows the suitability of e-procurement for educational purposes in e-commerce development.</p> / Report code: LiU-Tek-Lic-2001:19.

In this thesis, a semantically aided web service and restful service search mechanism is presented that makes use of an ontology. The mechanism relates method names, input and output parameters for ontology guided matches and offers results with varying relevance corresponding to the matching degree. The mechanism is demonstrated using an experimental domain that is tourism and travel. An ontology is created to support a set of web services that exist in this domain.

The main subject of this master thesis is the Service-Oriented Architecture (SOA). It shows a complete overview of Web Services in terms of realisation of a SOA. The thesis mentions what is already done and what else remains to ful ll the basic SOA principles. Then, it reviews Java EE platform tools used to deal with the Web Services. Next, it introduces the Java Management Extensions (JMX) technology as a solution of the web service's area - SOA governance. Moreover, it examinates the possible usage of JMX for the web service's management and monitoring issues. Finally, it implements an exemplary web services management and monitoring application on GlassFish server for testing purposes.
