The EJB3 docs show how to do this:
However, I just tried it and couldn't make it work with a Seam application. I don't know if this is an EJB3 issue or a Seam issue. I'll try and play with it some later, but in the meantime, maybe the docs link will help some.
Could not get it to work yet. Any success anyone else?
Ask in the EJB3 forum.
