In a Session Object when I use the setAttribute method how much of data or how many objects can I store in a session object.

putValue() has been deprecated in v2.2 of the Servlet spec. setAttribute() is a straightforward replacement of it. Ditto getValue() and removeValue() versus getAttribute() and removeAttribute().
Regarding the original question, there is no fixed limit to the number and size of objects you store in the session. Of course, your application will need lots of iron if your session-bound objects are many and/or bulky.
24/7 environments typically use clustering with session fail-over, which implies that everything you bind to the session is replicated into a safe location. Therefore there may be more overhead to storing something in the session than you might realise.
