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 set an attribute in a session. You have to retrieve it from a session:

Object sss = session.getAttribute("MyAttribute");

And since you are dispatching the request, you actually don't need a session. You can set the attribute in a request object in your servlet:

request.setAttribute("MyAttribute", "test value");

Then read it as you are already doing in you JSP.
