From the specs...is ok but I read in the book EJB 3 in Action on Subclassing rules for Session beans?? Here is what it says...
quote:A session bean class can subclass another session bean or any other POJO.
For example, a stateless session bean named BidManager can extend
another session bean PlaceBidBean in the following way:
@Stateless
public BidManagerBean extends PlaceBidBean implements BidManager {
...
}
A session bean class must not have a superclass that is itself a session bean class.
I am not able to understand how is this possible? Does the container take care internally all such issues? But how?
is it necessary for reading after chapter 12?
