How can I include sessions in JSP, Java Beans and Servlets?
I am using JSP model 2 architecture to seperate business logic from presentation.
using MVC (Model(java bean) View(jsp) Control(servlet))

At jsp:
<%@ page session="true"%>
or if you don�t want to create one
<%@ page session="false"%>
note that the true value is the default and if you wanna use a session in your jsp you don�t have do do nothing
at servlets:
HttpSession s = request.getSession(true);
this command creates a new session if one already is not created and if so just recovers the session.

HttpSession s = request.getSession(false);
this command recovers a session already created but if one doesn�t exist don�t create one.

and you can use:
setAttribute(String name, Object value);
to bind your javabeans to the session
and then recover them with:
getAttribute(String name);
and don�t forget to cast it back to it�s type.
I agree. Here's the link: http://aspose.com/file-tools
