Welcome to Remoting.

You want to look at the particular Throwable that comes back, its type and its description.  If a problem occurs in transit, you might get an IOException. If the server side handler throws an exception, that exception will be transported across the network and re-thrown by Remoting on the server side.

Throwables generated during callback handling are wrapped in a CallbackHandleException.  You want to extract the Throwable embedded in the CallbackHandleException and apply my previous remarks.

By the way, when I get an exception I don't recognize I often just google it and get lots of useful information.
