Shiva,
I don't think Oryx handles jPDL: Oryx was built specifically to be a BPMN 2.0 editor.
More importantly: would you mind posting your questions on the forum -- and not posting them as a comment to this web page? It's a little confusing to the rest of us!
If you post your question to the forum, the likelihood that you will get a good and correct answer will go up!
You can find the forum here: http://community.jboss.org/en/jbpm?view=discussions
Thanks very much for this,
Marco
