Web services-related problems can occur when your application acts as a Web services client to a remote Web service or as a Web service that is accessed by external clients. Symptoms of a Web services problem would include:

- Web services errors and exceptions that appear in the JVM logs

- Unexpected Web services behavior

- Problems with Web services tooling, such as the Java2WSDL and WSDL2Java scripts

- Error or warning messages that begin with WSWS.

This paper covers problems that occur during development of Web services applications (WSDL2Java errors) and deployment of these applications to WebSphere Application Server. It also covers problems that occur in the Web services engine.

It does not cover problems with Web services gateway, service integration bus, WSIF, or Web services security.

It is applicable to WebSphere Application Server on distributed platforms, i5/OS, and z/OS.
