Hi,
Could any one explain the advantages of using abstract bean class in ejb2.0. What is the flexibility in using it.
Regards,
Raju

The deploy tool (i.e. container) needs to subclass the CMP bean and implement the get/set methods which may not have an implementation (making it an abstract method) since a class with abstract methods must be marked abstract, the class must be abstract also.

The abstract bean classes are a convenience for the server, not for you as the developer.
