Subject RE: Using OpenJPA within an "old" J2EE1.4 container with managed transactions?
Date Mon, 05 Feb 2007 21:09:24 GMT
Looking at the trace, it looks like OpenJPA is being deployed correctly when you used java:comp/UserTransaction:

> 156  INFO   [RMI TCP Connection(7)-192.168.0.6] openjpa.Runtime -
> Starting OpenJPA 0.9.6-incubating

This means that OpenJPA loaded the configuration and initialized.

This means that we were able to connect to the database and figure out that you're using MySQL.

4)

It looks like IMSSystemBean.initializeJPA() is trying to invoked EntityManager.getTransaction().
Since you're using JTA, you're not allowed to use getTransaction(); all transaction management
must happen through container-managed transactions or bean-managed transaction code.
