With the new EJB 3.1 spec is it possible to inject an EJB into a pojo? I know in EJB 3.0 the @EJB annotation could be used to inject an EJB but this did not work on simple pojos.

If it is not do I have to look the bean up in JNDI as I know you cannot simple use the new keyword.

Injection of EJB into an POJO is possible IF you use JSR-299 (Java Contexts and Dependency Injection) i.e. if your POJO is a CDI managed bean. In that case, you could do:

@Inject MyEJB service

But this is not an EJB 3.1 feature, this comes from CDI. And if you're not using CDI, you'll have to do a lookup.
