Session handling in Jsp

[Sarath Koiloth Ramath]

Hi Friends,

How session is handled in jsp ? A interviewer asked me this question.What exactly he meant by this question?
I answered as session is implicit object ,So it will automatically avaliable.or if we make session=false.it will not participate in the session.Does i made any sense.

Thanks in advance

I believe that the interviewer was looking for how sessions are maintained by the container.

I *think* he means to ask about Session Management in JSP:
By default, all JSP pages participate in HTTP session.
The HttpSession object can be accessed within scriptlets through the session implicit JSP object.(This is what you replied...Extention to that:)
Sessions are a good place for storing beans and objects that need to be shared across other JSP pages and servlets that may be accessed by the user.
The session objects is identified by a session ID and can be stored in the browser as a cookie.
You can store any valid Java object by identifying it by a unique key like this:
<%
Test test=new Test();
session.setAttribute ("test",test);
%>
And you can retrieve it on all JSP pages:
<%
Test newTest= (Test) session.getAttribute ("test");
%>
I am not sure but this might be the answer...
Yeah right..my mistake..

Just a little info, putValue and getValue are replaced (deprecated) by setAttribute & getAttribute methods as of servlet 2.2 spec.
