How can I set a session variable in a servlet and get it in a JSP?

Question

I\'m learning java and try to pass some variable from servlet to jsp page. Here is code from servlet page

@WebServlet(\"/Welcome\")
public class WelcomeServl         


        

Answer 1

you are getting if from request not session.

It should be

session.getAttribute("MyAttribute")

---

I suggest you to use JavaServer Pages Standard Tag Library or Expression Language instead of Scriplet that is more easy to use and less error prone.

${sessionScope.MyAttribute}

or

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

you can try ${MyAttribute}, ${sessionScope['MyAttribute']} as well.
