Listener Question

[Sethu Prem]

Can somebody explain me the difference between
HttpSessionBindingListener and HttpSessionAttributeListener

1. Do they differ only by the object type they handle ?

2. Is there any order in which the listeners are invoked when a session
is being invalidated or being destroyed ?

Thanks
SP

An object of the class that implements HttpSessionBindingListener interface will be informed when it is added/deleted (bound/unBound) from the session.

An object of the class that implements HttpSessionAttributeListener interface will be informed whether an attribute has been added/removed/replaced from the session.

HttpSessionBindingListener will be invoked before HttpSessionAttributeListener when an Object is bound/unBound from the session.
