Info

More information The Web site of the UDDI organization is rich in content; you can find all UDDI specifications there; for example, the data model and API for Versions 1 and 2. Moreover, there are technical white papers, a best practices section, and an informative list of frequently asked questions: http://www.uddi.org Two registries that you can take a look at are: ► UDDI Business Registry http://www.ibm.com/services/uddi The UDDI Business Registry is an open, e-commerce service registry maintained by a group of companies, called operators, that have pledged to share all public information about registrants among themselves and with users of the service and to maintain interoperability among the multiple peer nodes of the UDDI service network. ► IBM Test Registry http://www.ibm.com/services/uddi A registry for developers to experiment with the technology and test their services. It is worth noting that these registries use a slightly different terminology than the UDDI object model exposed to API programmers: ► Business service instances are called businesses. ► Business services are called services. ► Binding templates are called access locators. ► tModel instances are called service types. 11.2 Studio Site Developer support for Web services Site Developer facilitates the following Web services development tasks to help you build and deploy Web services-enabled applications for your dynamic e-business across a broad range of software and hardware platforms used by today's businesses. ► Discover — Browse the Universal Description Discovery and Integration (UDDI) business registry or a Web Services Inspection Language (WSIL) document to locate existing Web services for integration. ► Create or Transform — Create Web services from existing artifacts, such as JavaBeans, Web sites that take and return data, DB2 XML Extender calls, DB2 stored procedures, and SQL queries. 366 IBM WebSphere Application Server - Express V5.0.2 Developer Handbook
► Build — Wrap existing artifacts as Simple Object Access Protocol (SOAP) and HTTP GET/POST-accessible services and describe them in Web Services Description Language (WSDL). ► Deploy — Deploy the Web service into the WebSphere Application Server or Tomcat test environments. ► Test — Test the Web service as it runs locally or remotely. ► Develop — Generate a sample application to assist you in creating your own Web service client application. ► Publish — Publish your Web services to a private or public UDDI business registry advertising your Web services so that other clients or businesses can access them. ► All Web services support is based on open standards such as UDDI V2, SOAP 2.3, WSDL 1.1, and new support for WSIL 1.0. ► Support Apache Axis 1.0 runtime. ► WSDL Editor — This is a graphical tool for editing WSDL files and embedded XML schemas. ► Enhanced Web Services Explorer — With support for discovering, browsing, invoking, and publishing WSDL. ► Support for creation of WS-I compliant Web Services. ► Command line tool for creation and consumption of Web services. 11.2.1 Web service preferences Studio Site Developer allows you to set different Web services properties within the workbench. To set any of the Web services preferences listed below, follow these steps: 1. Click Window -> Preferences to open the Preferences dialog. 2. Expand Web services, and click the preference category that you want to set. 3. Select the check boxes that you want to set as the default when creating your Web service. 4. Click OK to apply the changes and close the Preferences notebook. Backward Compatibility The Backward Compatibility preferences enable you to use options that are compatible with previous WebSphere Studio releases. This preference only applies if you are using Web services that use the IBM SOAP runtime. Chapter 11. Working with Web services 367
