It all makes sense. We just don't have that much experience configuring/using JTA or even JNDI for that matter. The biggest reasons for that were simply a) we never had a specific need and b) wanted our apps to come quickly for our developers with minimum configuration requirements that may vary by environment (test or development). However, Using these technologies is probably long overdue, so i'll probably try switching to JBoss as our development app server (instead of Tomcat), and figure something out for Junit. thanks for the explanation.
