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.

Why open source matters for Web Services and SOA

Page 6: Developing Web Services with Eclipse Arthur Ryman ryman@ca.ibm

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

Web Services are About Interoperability

Interoperability with Multiple Vendors

?

? Different implementation of standards ‘Value add’ proprietary extensions Implementation of a web service does not conform to standard Result: Lots of interoperability testing

Page 8: Developing Web Services with Eclipse Arthur Ryman ryman@ca.ibm

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

Page 9: Developing Web Services with Eclipse Arthur Ryman ryman@ca.ibm

Learn from the Past: Success of the Internet

Early 1990’s 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

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

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.

About Eclipse

Eclipse is an Open Source universal tool integration platform Contributed by IBM Eclipse Foundation was formed in 2004 as an independent legal

entity Eclipse is implemented in Java but is language neutral Eclipse has excellent Java development tools and is rapidly

becoming the most popular IDE Eclipse has a highly extensible plug-in archtecture

Extension points and extensions Commercial products like WebSphere Studio and Rational

Application Developer are based on Eclipse
