How to return application exception in RMI binding?

[Sun Yang]

Hi,
I want to get an application specific exception (which extends
java.rmi.RemoteException) from calling a rmi binding service. But the
exception always wrappered in a InvocationTargetException.

RMI spec supports remote exception. I am not sure if I missed something in
the composite configuration or Tuscany doesn't support throwing the
RemoteException directly.

In RuntimeWireInvoker.java, I find the following code which relates to the
exception handling.
            Object body = resp.getBody();
            if (resp.isFault()) {
                throw new InvocationTargetException((Throwable)body);
            }
I guess the wrapping here is the cause of the exception wrapper.

Best Regards,
