If you want to be JEE5 compatible, define one WAR and one EJB inside
EAR and use JAX-RS in WAR project (not in EJB like you wanted),
referencing EJBs from within your JAX-RS classes. This will suck a
little, as you will have to do write one class for JAX-RS view, one
local interface to access your EJB, like this:
app-core-api.jar -> where are EJB local interfaces and other common stuff,
app-core-ejb.jar -> the EJB module - implementation of your core API,
app-web.war -> the web module, the JAX-RS access to your application.
However it is exactly the same situation as when referencing EJBs from
within servlets, so JAX-RS or plain servlets - accessing EJBs in JEE5
can happen only through interfaces.
In JEE6 you can merge app-core-ejb.jar with app-web.war and there is
no need for app-core-api.jar in that case.
