I have a JSp where I want to add an object to the session and then forward it to a java class. With servlets we have this kind of code

HttpSession session=request.getSession()
session.setAttribute("user",user);

RequestDispatcher dispatcher=getServletContext().getRequestDispatcher("/url");
dispatcher.forward(request,response);

How do I do this in JSP. ?

Why would you want to do this?

JSPs are view components. Why move this controller code from a servlet, where it belongs, to a JSP, where it does not?

The bigger question is why are you forwarding from a JSP? A JSP is usually the "end point" of a request that formats the response sent to the browser.

In a web app following modern patterns, it's a rare thing to forward from a JSP -- in fact, I cannot recall the last time I did such a thing.

You mentioned servlets, so I assumed that you were following a Model 2 pattern. Is this not so?

As Bear mentioned why are you using a JSP to do this?
Anyways this can be done in a JSP as follows(but never do this,it is supposed to be a view component)
