Hi,
I've managed to reproduce the problem with a modification of one of the
Test examples. If you add the following line to Test56 around line 90
histogram_ref.getData().local();
and run 55 then 56 you'll see a related exception with the latest
visad.jar. It works with an older version. Did some class lose it's
Serializable implementation?
Thanks,
Doug

Yes, indeed. The very same visad.jar, in fact, since my client and
server are running on the same machine in this case.

Hi Doug,
Are the client and server both using the same version of visad.jar?

Hi,
When I switched to the latest visad.jar file I started getting
exceptions like below. It works fine with an older version of
visad.jar. I have been careful to make sure the rmiregistry, server,
and client are all running with the same classpath. I have a
RemoteServerImpl (with RemoteDataReferenceImpls) bound to my server
but when I try to access the data from my client:
java.rmi.UnmarshalException: error unmarshalling return; nested
