Migrate Web services

If you have used the Apache SOAP support to create Web services client applications in WebSphere Application Server Versions 4, 5, or 5.1, you may need to migrate your applications or the security files for your applications. The following table summarizes the Web services supported by WebSphere Application Server.

WebSphere Application Server Version	Web services supported
4.0	SOAP 2.2
5.0 and 5.0.1	SOAP 2.3
5.0.2 or later	J2EE (JSR 109)
6.0	J2EE (JSR 109)

Note: The SOAP 2.2 and SOAP 2.3-based implementations that were available in WebSphere Application Server Version 4.0.x, 5.0, and 5.0.1 have been deprecated. IBM recommends that applications using these SOAP implementations migrate to the Web services for J2EE (JSR 109) support provided in WebSphere Application Server Version 6.0.

For more information on migrating your Web services, see these topics:

Migrating Apache SOAP Web services to Web Services for J2EE standards
This topic describes how to migrate your Version 5.0 and 5.0.1 Web services to the J2EE standards supported in WebSphere Application Server Version 6.0.

Notes:

• IBM recommends that new Web services be developed using the J2EE standards. For more information, see Implementing Web services applications.
• Security cannot be directly migrated from SOAP 2.3 to the J2EE standards. After you have migrated your Web services to the J2EE standard, see Securing Web services for version 6 applications based on WS-Security in the Web services topic to secure your Web service.
