Migrate Web services

If you have used the Apache SOAP support to create Web services client applications in WAS Versions 4.0 or 5.0, you may need to migrate your applications or the security files for your applications. The following table summarizes the Web services supported by WAS.

WAS 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)
