Lookup for EntityManager

[vamshi.a]

I have created an EAR which has EJBS and entities. In one of the session bean I am calling Hibernate validator class  which requires EntityManager. In case of JBOSS 6 I have used the Intialcontex.lookp("java:/comp/em) to get the entitymanager.How can I acheive the similar functionality in jboss 7

   public EntityManager getEntityManager() throws Exception {

        InitialContext ctx;

        try {

            ctx = new InitialContext();

            return (EntityManager) ctx.lookup("java:comp/env/em");

        }

        catch (NamingException e) {

            // This is critical internal issue and it is not probably to see in case of proper deployment. So no translation for message applied.

            String errMsg = "Could not acquire EntityManager from bean context. Reason: " + e.getMessage();

            log.error(errMsg);

            throw new Exception(errMsg);

        }

    }

What class is that method from? If it's some container managed class, you can use injection. Or if you are calling some class from a container managed component, then the component can setup the ENC (via deployment descriptor or annotation) and the other class can look it up.
