Question about MemoryFileSystem and InMemPersistenceManager

[Jérôme Verstrynge]

 Hi,

I am a newbie to jackrabbit. I want to create an in-memory repository to 
perform tests. I have seen 
http://jbossdna.blogspot.com/2008/02/unit-testing-jackrabbit.html, but 
the described method seem to imply that initial repository.xml files and 
directory must be created. This is not really in-memory.

Is there any method to create a pure in-memory (transient) repository 
using java code only? Can anyone provide a fulll code example?

Thanks,
