Hi there
Well I have a rmi server running in an eclipse plugin.
All worked fine until I added some classes to my serialized objects from
the org/eclipse/core/runtime plugin. (Status and CoreException)
Now when invoking Naming.rebind I'll get an Error.

Any Idea ?

Thanks in advance

Did you define org.eclipse.core.runtime as a required plugin in your
plugin.xml file?

yap.
It wouldn't compile otherwise.

I guess it has something to do with the rmi serialization.
Is there anything I should look for ?

RMI support in eclipse plugins still puzzles me a lot. My uneducated
guess would be that you first, find whether the exception is thrown by
the client or by the server. I case it is thrown by the client (the
server is your plugin), try adding the code plugin to the codebase
exported by the plugin server.

Thanks
this might be the problem.

I manually added runtime.jar to the <runtime> element in my plugin.xml
(... <library name="lib/runtime.jar"/> ...)
and it seems to work.

I still don't no why.
I first thought it has something to do with running in the development
mode. But adding the lib worked outside eclipse too.

Hi, Matthias:

That problem comes out from the Eclipse plugin class loading mechanism.
Eclipse plugin's class loading is different from general java application.

Eclipse plugin even will not load the classes you put in the JRE's
extension libraries.
