Hey,

I have ear that contain jar Model,Infra,Server.

I want to have persistence unit XXX that has all the entitis under Jars - Model,Infra

And persistence unit YYY that all the entitis under Jar - Server.

Server has DAO that need to work with the two persistence units.

Where should i put the META-INF files?

Is it ok to has entites in Jar that dosnt declared as ejb jar?

Thank you

you can do that by refering to an external jar using the <jar-file> (i believe) element of a persistence.xml

The jar containing the persistence.xml has to be an ejb-jar

Hey,

I success to include entites from another jar in the persistence , but the problem is that my DAO's from another jar cant reference to this persistence unit.

I get an exception in the deploy:

Code:

14:01:55,513 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:ear=insite-1.0-SNAPSHOT.ear,jar=serverInfrastructure-1.0-SNAPSHOT.jar,name=AuditorDao,service=EJB3
  State: NOTYETINSTALLED
  I Depend On:
    persistence.units:jar=ver-1.0-SNAPSHOT.jar,unitName=BRL-Server

The DAO in the other jar failed to find the persistence unit which declared in the "server-1.0-SNAPSHOT.jar".

Here is the injection:
@PersistenceContext(unitName="server-1.0-SNAPSHOT.jar#BRL-Server")

Code:

Thank you

Hi,

Why don't you just define the Persistence.xml at the top level in the ear, then all "sub jars" should be able to use it.

You just need to pack a jar file in $EAR_ARCHIVE/lib, you will need a class to put in you jar file just with an empty constructor, and pack the Persistence.xml in the META-INF dir of the jar

Cheers,

Andy

Hi,

Thinking about maybe you won't, but i meant just some simple class like below:

Code:

public class foobar {
   public foobar() {
      super();
   }
}

but maybe it will work as a manifest only jar, but you will have to test this.

Cheers,

Andy
