Hi Ranchers,

I'm working with Java EE 5 and using the Java Persistence API 1.0. I have two databases, one db2 and one mysql. The connection to them are set properly and I have one table in each of these databases. I also have one Entity class for each table. The issue is that I'm getting troubles to connect both dbs in one operation. Here's my persistence.xml file:



And here's my session facade:



I'm getting the following exception:


I'm wondering if this problem is related to the fact I want both to be container managed... Any ideas on how to resolve this?

Thanks in advance

Aurelio

The exception you are getting means that your database connections do not support distributed transactions. Check the drivers for XA compliance, and see, for example, this discussion.
