Hi Sripada
What I meant was -- the ejbCreate,ejbFindBy... methods return the PK object
-- so if the child class wants to return a diffrent PK class then atleast
that PK class has to be the subclass of the base classes PK class. This
restriction is only for entity beans and not for session beans.
BTW its nice to know that u are from Wipro --- I worked for Wipro for 2.5
years and left a few months back (and obviously repenting a lot!!). Are u in
ECD group??
cheers
Ana

Hi Ana,
I did not understand "U have to be a bit careful in writing the ejb* methods
in
the child class" -- I cannot imagine the kind of difficulties one would face
becasue of inheritance.
