How do I configure TransactionManager to use the JTS Driver in 3.2.3?

OK, I'm pretty close to integrating my Toplink 9.0.4 components with JBoss 3.2.3. I'm pretty sure when I get the TransactionManager swapped over to using the JTS driver, it should start working. Does anybody know how to do this?
Here's the error I'm seeing:
