Nothing wrong with you. Entity beans are easy to use for developers. But their performance is a problem. -jabber(jabber); 2001-3-13 (#32801@0)
If you use Container-managed beans, the ejb compiler will generate all the JDBC code for DB access.... -jabber(jabber); 2001-3-13 {129} (#32809@0)
However, these compiler generated code is not always optimized for your requirements. Too much overhead. Seldom good performance.

yes,Ihave to use CMB because BMB for me is too hard -wendywendy(wind); 2001-3-13 (#32920@0)
