Thanks, its good to know that I'm not alone.

I have part of my code working. I can open a prebuilt  repoistory and 
create a model.
When I go to run a query it fails. I have checked the version number, at 
runtime, and I'm using the jena that came with cocoon.
It seems to not use my java classpath at all.
I have look in the jena-2.1.jar and it is a lot different than the one 
that came with jena-2.5.2

I will try to reconfirm that I have a problem switching jena. I assume 
that you are using what came with cocoon. Are you doing any sparql querries?
