Hi All,

I am new to web services.I am encountering InvocationTargetException while I am generating java source code from WSDL file using Axis code genarator plug in.I am encountering this problem at time of clicking on finish button(after giving wsdl path,output folder for generating java source code).

I am using JbossIDE for Eclipse 3.1,jboss-4.0.4.GA and java5.

How can I get rid of this problem.What kind of configuration I have to do to run sample web services application.

Please help me on this issue.Its urgent for me.

Thanks in advance..
