Hi,
Yes you can subclass a bean . But it raises a lot of issues that you have to
take care of like :
If you have defined a finder method in BMP, then in the derived class you have to
match the method signature . this means you even have to use the same primary class as
return value.
Also a HI should return the same RI in life cycle methods in super class and derived
class.
You can use inheritance in EJBs to share common code, but before that you have to
consider these various issues and consider if it is worth doing it. If there is some
common code to be shared then it is better to use Adapter classes
Cheers,

Subject: Subclassing a bean
Hi
I have doubt regarding subclassing an Enterprise bean (either session
bean
or entity bean). Do we able to subclass a bean ?? I am under impression
that
we can't derive a class from a bean. Please clarify somebody.
Thanks.
