try
{

// Init

ABTest2
---------------------------------------------
package org.jboss.test.cmp2.relationship.manyToManyBidirectional;

import java.util.Collection;
import java.util.Iterator;
import javax.naming.InitialContext;

import javax.rmi.PortableRemoteObject;
import javax.naming.InitialContext;

public class ABTest2 //extends EJBTestCase {
{
public static void main(String[] args)
{
try
{

InitialContext jndiContext = new InitialContext();
ControllerHome controllerHome= (ControllerHome) jndiContext.lookup("ejb/Controller");

// Inizializzazione

Controller c = controllerHome.create();

System.out.println("esecuzione test1");
c.test2();
}
catch (Exception ex)
{
System.out.println(ex.toString());
}
}
}

These are the steps:

1) start JBoss3.0
2) compile and deploy the ejb.jar
3) execute ABTest1
4) restart JBoss3.0
5) execute ABTest2

then JBoss report the error.

Where I make a mistake?

Thanks
