A very good question that arose from the "Servlets vs. EJB" thread is this: When should CMP be used? For example: What is CMP best suited for? Is it only advantageous when designing the DB from scratch? Is an effective schema possible if CMP doesn't directly support any mapping except the following: one-entity-bean-equals-one-row-in-one-table (with a one-field primary key) Jim _______________________________________________ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
