Hi,
I am new to WTP. I am trying to create a webservice for my java class using option "Generate default services.xml" in Eclipse WTP, Axis2 server. My java class is having four methods in which two has return type String, and other two are void, and all the four methods throws Exception.
I am following the tutorial http://www.eclipse.org/webtools/community/tutorials/BottomUp Axis2WebService/bu_tutorial.html for creating my project and the web service client.
Now when i am running my client class it throws exception as java.lang.UnsupportedOperationException: An access occurred that is not valid.
The exception trace is :

[ERROR] An access occurred that is not valid.
java.lang.UnsupportedOperationException: An access occurred that is not valid.

I have also noticed that this problem occurs only when my java class contains methods void and non-void type that throws exception.
Can anybody tell me how to resolve this?
The versions i am using are Axis2-1.5, JDK 1.6.0_16, tomcat 5.5

Girish B.

Hey Girish,

This sounds a lot like this axis2 bug:
http://issues.apache.org/jira/browse/AXIS2-4408
