At least, we can say that the technologies used to implements EJB3 are very different of the ones used for EJB2... But, in all the cases no Java reflexion is used on the server side (this is usually the costly thing). On the client side, this is a Java proxy (reflexion) that is registered on JNDI for EJB3, so here we may have a performance penality ... In EJB2, the stub was directly registered in JNDI (no reflexion)... Hope it helps... --G > > regards, > hans >
