Difference Between JSP and Servlet Session

[Jimi Parekh]

Hi,
Is there any difference between JSP and Servlet Sessions?

[Ulf Dittmer]

Not really, especially as JSPs are generally implemented as servlets. One difference is that JSP by default creates a session, while servlets do not.

Yes as ulf said by deafault no session is created but you can create a session by


<%@ page session="true">

You've got it backwards.
By default, JSPs create a session for you.
If you don't want your JSP to create a session, you have to use
<%@ page session="false">

If the application server creates an HttpSession for a user, that HttpSession is the same session used by every JSP and Servlet that user accesses. If you stuff some great data in the HttpSession in a Servlet, the client will be able to yank that data out of the HttpSession in any JSP or other Servlet in the application. Well, until their session times out, that is.

Here's more info on HttpSession objects:
