2 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Abstract The recently created Web Tools Platform Project extends Eclipse with a set of open source Web service development tools and APIs. This talk gives an overview of the project and focuses on its Web services support. The project is divided into two subprojects: Web Standard Tools and J2EE Standard Tools. The Web Standard Tools subproject contains support for XML Web Services, including tools based on standards defined by W3C, Oasis, WS-I and others. The J2EE Standard Tools subproject contains support for standards defined by JCP, such as JAX- RPC and JSR-109, and for reference implementations of these standards, such as Apache Axis. The project contains both a set of tools for Web service developers and a set of APIs for Web service tool creators. The talk includes a demonstration of the tools.

6 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Web Services are About Interoperability Company B Company A

7 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Interoperability with Multiple Vendors Vendor A Vendor B Vendor C Vendor B Vendor A Vendor C ? ? Different implementation of standards Value add proprietary extensions Implementation of a web service does not conform to standard Result: Lots of interoperability testing

8 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Where problems may arise Implementation of Web Service Runtime (SOAP Engine) Each vendor implements standards differently Different interpretation of standards Value add proprietary features Optimization to certain environments (security, transactional, reliability, XML compression) Implementation of specific web service Is the web service using well formed WSDL? Does the web service support the WS-I Basic Profile? E.g. exclude SOAP encoding

9 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Learn from the Past: Success of the Internet Early 1990s Internet starts to take off TCP/IP and HTML become accepted standards Most major software vendors develop HTML web servers Apache evolves from NCSA and becomes dominant web server It was good and free! Commercial friendly license Software vendors adopt Apache or ensure interoperability IBM, Oracle, etc adopted Apache The result: an Internet which is pervasively available and free Open source provides the platform

10 Developing Web Services with Eclipse | Web Services and SOA China, Beijing

11 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Key to Success for Interoperability Open Standards OASIS, W3C, WS-I Pervasive open source reference implementations Forces vendors to adhere to standards to ensure interoperability Royalty free software promotes quick adoption Open source implementation must be commercial quality Freely available tools to create, test and deploy web services Ensures web services conform to standards, ex WS-I Basic Profile

12 Developing Web Services with Eclipse | Web Services and SOA China, Beijing Open Source Platform Open Standards Open Source Runtimes OASIS, W3C, WS-I XML, SOAP, WSDL Consistent Meta-data ObjectWeb, Apache Consistent execution environment Open Development Platform Eclipse, Mono, Netbeans Consistent implementation and validation environment

13 Developing Web Services with Eclipse | Web Services and SOA China, Beijing The Role of Eclipse in Web Services Open Source implementations of standards- based runtimes, tools, and testing frameworks are vital to the pervasive success of Web Services.
