101 Which listener need not to configure in DD?
A HttpSessionActivationListener
B HttpSessionBindingListener
C HttpSessionAttributeListener
D HttpSessionListener


Answer
B

We don't need to declare the HttpSessionBindingListener in our dd.

In errata page it is given that HttpSessionActivationListener should not be declare in DD

Is option A a valid answer
