I am a little confused so please bear with me. I have two persistence units myPU1 and myPU2. Each is defined in a separate jar file. I want to get both of these persistence units into JNDI. I also want both persistence units in the same entity manager factory (if that is possible) I know that I have to use one of the following properties in my persistence.xml but I am not sure which or if I need both: | <?xml version="1.0" encoding="UTF-8"?> | <persistence xmlns="http://java.sun.com/xml/ns/persistence" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xsi:schemaLocation="http://java.sun.com/xml/ns/persistence | http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" | version="1.0"> | | <persistence-unit name="myPU1" transaction-type="JTA"> | <jta-data-source>java:myDS</jta-data-source> | <properties> | <!-- Store entity manager and factory in global JNDI --> | <property name="jboss.entity.manager.jndi.name" value="myPU1"/> | <property name="jboss.entity.manager.factory.jndi.name" value="myPU1"/> | </properties> | | </persistence-unit> | </persistence> | I have another file that is identical except for the persistence unit name (myPU2). Can I bind both of those to the same factory? View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4270294#...
