jcr-rmi problems

Tomcat server log shows that the RMI Objects are created in the RMI registry.

I can retrieve an instance of the Repository factory OK via:

ClientRepositoryFactory factory = new ClientRepositoryFactory();
final Object o = factory.getRepository(s);

but when I try to "login" to the "default" workspace, I get the following
RMI error:


org.apache.jackrabbit.rmi.client.RemoteRepositoryException: error
unmarshalling return; nested exception is:

I just had a BIG   "A H A A A"  - I forgot about that.  I had a similar
problem with Unix classpaths.  Thank you VERY much for your help.

This is a common error when using RMI. It took me some time to find out 
what's happening there when it occurred to me the first time. The "and" 
comes from the folder where your classes are which is probably something 
beneath "C:\Documents and Settings". Moving your application to a folder 
without spaces or setting the system property 
"java.rmi.server.useCodebaseOnly" to true should solve the problem.

Cheers,
Christoph
