Eclipse RCP, RMI and Bundles - eclipse-rcp

Question

I'm trying to combine Eclipse RCP with RMI. For that purpose I created six bundles:
(In parenthesis are dependencies)
Core: Interfaces for client and server
Server(Core): Server implementation and Registry start class
ServerApp(Server): GUI client which basically just instantiates the registry starter (and starts it on Activation)
Client(Core): Client implementation
ClientApp(Client): GUI client
Now I started the serverapp, but I got a
Caused by: java.lang.ClassNotFoundException: core.rmi.CallbackServerInterface (no security manager: RMI class loader disabled)
Now I started the server with
-consoleLog -Djava.security.policy=java.policy -Djava.rmi.server.codebase=file:${workspace_loc}/core/
(My java.policy file is in the core plugin).
I thought the problem was the classpath. So I made core and server buddies:
Eclipse-BuddyPolicy: registered
in the core bundle manifest file and
Eclipse-RegisterBuddy: core
In the server bundle manifest file.
Which didn't help, since I got the exact same error.
Does anyone know where I could have gone wrong on this one?

Answer 1

So apparently the problem was, that OSGI uses its own Classloader. So before we do the Naming bind we need:
Thread.currentThread().setContextClassLoader(
this.getClass().getClassLoader());
After this, the server works like a charm, and the client can connect.
