Hi Arun ,
thank you for replaying ,
This is true that the return value is different than the expected value , but there are with the same type.
lets say the expected type is A and the actual type is B.
the B object extends the A object in both side.
The web service is implemented with .NET Env.
Is it possible that the .NET creating WSDL different from the java
expectation ? (the rpc and document/ literal differences ) .
As for the Q : Which method are you trying to invoke ?
Answer : I am trying to invoke the GetRollTreeMethod
As for the Q : You mentioned "extends component". Where is this class existing ?
Answer Both sides the java client and the .NET having the same objects.

Thanks again.
