btw... I tried what i suggested and i get a NullPointerException right when i execute createQuery on the SFSB's entity manager injected in the stateless bean... The same exact code works fine when executed from within the stateful bean. So, my question is: should it be possible? and if not, what's the best way of using an EPC and daos? Thanks!
