PersistanceUnit for the ear

jplessinger Dec 12, 2008 11:57 AM

I need to access my PersistanceUnit from the beans in mylogic.jar. I have an ear with the following structure.

myapp.ear
|-mylogic.jar
|-myentities.jar
 |-META-INF/persistence.xml
|-myweb.war

myentities.jar contains the persistance.xml and does not contained any EJBs. If I add myentities.jar as a module the PersistanceUnit is loaded by JBoss but the beans in mylogic.jar can not find the PersistanceUnit. If I add myentities to /lib it's not loaded at all.

Any ideas on how to load the persistanceUnit from mylogic.jar would be helpfull.

JBoss 4.2.1 (All of this is EJB3)
java 1.5_16

If anyone else has this problem and finds this post I find the solution here, took me a while to get the search terms right.

I should clearify a bit.

I like to keep my entity beans separate from my business logic EJB. I also use the entity beans in other applications. I created a jar containing the entity beans and a persistence.xml file

To inject the PersitanceContext into a sessoin bean I used the line below.

@PersistanceContext(unitName="XXXentity.jar#PersistenceUnit")

Yes the "XXX" is just random.

I also had to put the entity.jar in a
<module/>
section in the applicaton.xml file
