Pass variables from servlet to jsp

Question

How can I pass variable from servlet to jsp? setAttribute and getAttribute didn't work for me :-(

Answer 1

It will fail to work when:

1. You are redirecting the response to a new request by response.sendRedirect("page.jsp"). The newly created request object will of course not contain the attributes anymore and they will not be accessible in the redirected JSP. You need to forward rather than redirect. E.g.

   request.setAttribute("name", "value");
   request.getRequestDispatcher("page.jsp").forward(request, response);
   

2. You are accessing it the wrong way or using the wrong name. Assuming that you have set it using the name "name", then you should be able to access it in the forwarded JSP page as follows:

   ${name}
