[jboss-user] [Installation, Configuration & DEPLOYMENT] - @PersistenceContext injection from a different jar fails

[Nouredine13]

Hello,

I have a sample application with an EJB3 SLSB which is being injected with a PersistenceContext which is configured in a different jar file as follows :

package org.myapp.ejb.impl;

import javax.ejb.Local;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import org.myapp.ejb.AppManager;

@Stateless
@Local ({AppManager.class})
public class AppManagerBean implements AppManager {

@PersistenceContext (unitName="myapp_ejb3.jar#MyPU")
private EntityManager em;

public String getVersion() {
System.out.println("EM is " + em);
return "1.0";
}


}


The application is deployed as an EAR file in the following structure:

EJB3Persistence.ear
|
|--- META-INF
| |
| |----application.xml
| |

|--- myapp_ejb3.jar (contains the persistence.xml)
| |
| |--- META-INF
| | |
| | |--- persistence.xml
|
|
|
|--- another_ejb3.jar (contains the SLSB)
| |
| |
| |--- META-INF
| |
| |--- org.myapp.ejb.impl.AppManagerBean


Note that this application is deployed fine in JBoss-5.0.0.Beta4,

but with 5.0.0.CR2 the deployment fails.

Part of the exception is pasted below:

I found the same bug here : http://www.jboss.com/index.html?module=bb&op=viewtopic&t=146052

I applied the solution he suggested : jboss-JPA-deployers-1.0.0.Beta4, but this do not solve the problem!

if someone has an idea?

Thank's a lot.
