Subject Re: How to deploy JPA?

Unless someone changed the code a lot while I wasn't looking I don't  
think that will work.

  I think you need to
(1) make sure your pool module is an ancestor of your ejb app: the  
easiest way is to make it a dependency in the geronimo plan for the  
ejb app.  This has the same effect as the "ext-module" in daytrader.
(2) assuming you do want jta :-) use <jta-data-source>MyTestPool</jta- 
data-source>  or <jta-data-source>name=MyTestPool</jta-data-source>
