This tutorial shows J2EE developers how to use the IBM ETTK (Emerging Technologies Toolkit) to make any EJB a Web Service that will run on any application server. This tutorial also works with Apache Axis.
This tutorial is the first part of a series that introduces you to Web services concepts and technology, demonstrates how to practically apply these concepts using the IBM WebSphere SDK for Web services V5.1 (WSDK), and how to use Eclipse to create Web services using WSDK-supplied plug-ins. This tutorial also explores the current state of Web services technology. WebSphere Web Services Development Kit
Introduction to Web services and the WSDK V5.1 This tutorial shows how easy it is to convert existing Enterprise Java Beans components into Web services with the WebSphere SDK for Web Services V5.1 (WSDK). It demonstrates the ability of the IBM WSDK to convert a Stateless Session Bean in one easy step into a full Web service conforming to the requirements of JSR-109 - The Web Services for J2EE Architecture. The tutorial starts with a short examination of JSR-109 with regards to Enterprise JavaBeans components and then dives into using the WSDK plug-ins for the Eclipse IDE to convert an existing EJB component into a Web service.
Create a Web service from a Stateless Session Bean with WSDK V5.1 The Web Services Description Language (WSDL) is an XML-based format maintained by W3C used for describing a Web service in an implementation-neutral manner. It is the common thread that ties together the many different ways of creating and consuming Web services. This tutorial will give you a firm understanding of the purpose and mechanics of WSDL and how it is an essential part of making Web services interoperable. This tutorial includes labs that use the IBM WSDK plug-ins for the Eclipse IDE to create both Web services and clients starting with only a WSDL file. This tutorial will show you how the high level tools available in the WSDK can help you speed up your development of Web services when you are working with WSDL.
