EJB Dependencies

Anyone know of a plugin by which I can poll an entire codebase for EJB depdendencies? Basically, I've stepped into a position where the folk here were ignoring the JNDI ENC and I want to make the appropriate <ejb-ref> entries in <ejb-jar> but don't wanna scan the whole codebase for these dependencies nor do I wanna XDoclet the thing.

Any ideas?
