@PersistenceContext injection from a different jar fails
--------------------------------------------------------

                 Key: EJBTHREE-1252
                 URL: http://jira.jboss.com/jira/browse/EJBTHREE-1252
             Project: EJB 3.0
          Issue Type: Bug
          Components: injection
    Affects Versions: AS 4.2.2.GA
         Environment: JBoss-4.2.2GA, Windows 2003 Server, Sun Java 1.5
            Reporter: jaikiran pai


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

import org.jboss.annotation.ejb.RemoteBinding;
import org.myapp.ejb.AppManager;

@Stateless
@Remote ({AppManager.class})
@RemoteBinding (jndiBinding = "AppManagerBean")
public class AppManagerBean implements AppManager {

	@PersistenceContext (unitName="myapp_ejb3.jar#EJB3Persistence")
	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
 |	|
 |	|--- META-INF
 |	|	|
 |	|	|--- application.xml
 |	|	|	
 |	|	|--- jboss-app.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
 	
 
When this application is deployed in 4.2.2 the deployment fails with an exception. Part of the exception is pasted below. The relevant log files (ConsoleLog_Fail.txt and serverLog_fail.txt in the logs.zip file) are attached.

If i change the PersistenceContext injection, in the bean, to prefix 3 random letters to the unitName as follows:

@PersistenceContext (unitName="XXXmyapp_ejb3.jar#EJB3Persistence")
	private EntityManager em;

and deploy the application, then everything works fine (have also attached the successful logs ConsoleLogs_Success.txt and serverLogs_Success.txt in the logs.zip file).
