Container Managed Transaction

[bhama kumaran]

Hi,
I am trying to implement container managed transaction in WAS 7. I am directing container to manage transaction by injecting the entityManager. But whenever I am trying to persist entities inside try-catch block, and catching the exception,the transaction is not rolled back,even the code I wrote must initiate a rollback. But whenever I am trying not to catch exception by removing try-catch,the container is rolling back the transaction. Do it is the case that we must throw the exception from DAO to container without catching it?
Here is my code:

  
package com.test;

import java.util.Date;

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

@Stateless
public class Test implements ITest {

	@PersistenceContext(unitName = "cmtpoc")
	protected EntityManager em;

	public void insertData() throws Exception {
		EnErrors en = null;
		try {
			System.out.println("Inside Insert Data");
			en = new EnErrors();
			en.setErrorId(130L);
			en.setUserColumn("abc");
			System.out.println("Going to persist 1st set");
			em.persist(en);

			en = new EnErrors();
			en.setErrorId(127L);
			en.setUserColumn("abc");
//Inject exception
			System.out.println(1 / 0);

			em.persist(en);

		} catch (Exception ex) {
			throw ex;
		}
	}
}
 

Any help will be greatly appreciated.

It looks pretty weird to me, because you are just rethrowing a runtime exception...

Have you tried to setRollbackOnly in your catch code??

...
@Resource
SessionContext sc;
...
...

} catch (Exception ex) {
sc.setRollbackOnly(); //<---
throw ex;
}

...

Regards,

Manuel
