When something goes wrong on the server, GWT returns a StatusCodeException
to the client. It doesn't propagate the exception that occurred on the
server side, unless you explicitly declare it.
So how do you find out what went wrong? In your RemoteService
implementation, override the method doUnexpectedFailure() and log the
exception. GWT calls this method just before returning to the client.
@Override
protected void doUnexpectedFailure(Throwable e)
{
LOGGER.error(e, "Unexpected Failure while processing
Request");
}
