Sure :-) > Is there a plan for support polymormhism in EJB Cartdrige??? Its already in the EJB cartridge for AndroMDA 3.0. If I haven't overlooked something in the article (I've just skimmed through it and didn't read it thoroughly), the only real difference between their approach and the one in AndroMDA is that the AndroMDA EJB cartridge only allows inheritance from abstract base classes, not from concrete entities. The reason for this is even mentioned in the onjava article: "Not all EJB containers behave the same. Some vendors prohibit entity beans from extending other [entity bean] classes. This is due to the different ways the specification can be interpreted."
