I'm not sure what you mean.  Even though I advised against it, I
explained how to do it.

To be specific, you write an interceptor that scans the incoming
action instance for @EJB annotations.  For each annotation, you check
the HttpSession to see if you already have a reference for the
specified class.  If not, you do the JNDI lookup and store it in the
HttpSession for future use.  And finally, you inject the reference(s)
into the action and call the next step in the invocation chain.

Maybe someone else has some improvements, but that's the general way
it would work.
