[news.eclipse.platform.rcp] Classsloading Problem

[Christian Hager <ch.hager@xxxxxxxxx>]

Hello,


I'm trying to built an application using RCP and JavaSpaces. Currently 
I'm experiencing some classloading problems and was hoping someone here 
could maybe help me solve them.
So here is what the problem is. I have a worker which is an RCP 
Application and which is supposed to take entries from a JavaSpace 
process them and put the results back into the space.
The Problem is when I try to take an Entry from the Space and want to 
cast it I using the following code

TaskEntry task = (TaskEntry) javaSpace.take (taskTmpl, txn, 30000);

I get the following exception

java.lang.ClassCastException: org.ac.computegrid.TaskEntry
at org.ac.computegrid.worker.GenericWorker.loop(GenericWorker.java:123)
at org.ac.mvc.ExtThread.run(ExtThread.java:399)
at java.lang.Thread.run(Unknown Source)

I think the JavaSpace uses an RMIClassloader and the bundle does not 
which makes the classes different. But I have no idea what I can do 
about that. I was hoping anyone here has any idea of what I can do to 
make it work.

Thanks in advance for any help.
