Multiplas database with JBoss and EJB3

[bill.burke]

right now, you can only have one EntityManager per jar

If you are implement an EAR, then there is only one EntityManager per EAR.

This means that you can only have one datasource per EAR or per JAR.

Take a look at this doco here:

http://docs.jboss.org/ejb3/reference/hibernate.html

Bascially what you have to do is create a hibernate.properties file and put it in the META-INF of your EJB jar (.ejb3 file) or in your .ear.
