Java EE (Java Enterprise Edition) General Discussion

Hi all,

I have a jersey REST server and client, both sharing an annotated interface of the service. The service methods can throw custom Exceptions (say, a 'CustomException').
The client is calling the service by using a service-proxy of that interface, so it should be aware of all class-types that is used by the interface including the Exception types.
But when a CustomException is thrown by the server, the client does not get this type, but a more generic jax-ws Exception. I was assuming that for a proxy-service the Exception class will be recreated out from the response, but that seems to be not the case.

So is the only way to catch custom exception from the server to the same custom exception in the client by using an Exception-Mapper?
