When I run the generated client for a web service, I get the following error, which I can get rid of by using a primitive type (e.g. String) as the parameter to doSomething instead of wstest.test2.APIClass3, i.e. the SOAP server seems happy handling wstest.test2.APIClass1 as a return type, but not a similar class as a parameter type:
[SOAPException: faultCode=SOAP-ENV:Server; msg=type mismatch [java.lang.IllegalArgumentException]]
wstest.test2.APIClass1 wstest.test2.EmbeddedStatelessTest2Stub.doSomething(wstest.test2.APIClass3)
EmbeddedStatelessTest2Stub.java:89
void wstest.test2.EmbeddedStatelessTest2Stub.main(java.lang.String[])
EmbeddedStatelessTest2Stub.java:48
I am using JDeveloper9i 9.0.3 Preview and the standalone OC4J 9.0.3 that came with it. I followed the Oracle9i JDeveloper 9.0.3 Web Services Quickstart Install (http://otn.oracle.com/tech/webservices/htdocs/quickstart/quickstart903.html) to get OC4J running standalone. I had to register the stateless EJB provider, and the WEB services wizard didn't manage to include APIClass2 (an instance of which is contained in APIClass1) in the .dd so I added it manually which works fine with APIClass1 as the method return type.
Sorry for the length of this posting, but I wasn't sure which bits would be relevant.

I change the http port from 8988 to 8888 to get this working. Also, the generated referenced a new class APIClass31, also generated, but as it didn't make any difference to the problem I replaced it with APIClass3, which has essentially the same characteristics.
