Packaging EJB in JavaEE 6 WAR vs EAR

Question

Starting a new project and would like to know the pros and cons of packaging EJB in a WAR vs EAR.

Will JNDI still works when EJBs are in the WAR? efficiency? etc.?

Answer 1

So far this is what I got.

EJB in WAR

pros:

1. Simpler to develop and deploy

2. You can expose Session Bean methods as REST service with @Path annotation. See here

cons:

1. JNDI lookup is not supported, so I believe you cannot do RMI from another application client

2. As arjan pointed out it lacks modularity in design.
