OJB block clean up

[Joerg Heinicke]

In the block there is a WEB-INF directory including compiled classes. 
IMO that's not ok and from what I see I think it can be removed, but 
some possible useful files could be missing afterwards: OJB.properties, 
repository.xml and repository.dtd. The rest is already in the java 
directory AFAICS.

Antonio?
