Passing java variables from JSP to Servlet - return null values
1 Answer(s)      3 years and 4 months ago
Posted in : JSP-Servlet


I want to pass some variables from a JSP page to a servlet. These variables are from the java code of my JSP. In JSP page I did,

String msg="hello"; request.getSession().setAttribute("msg",msg);

String strViewPage="MyServlet"; RequestDispatcher dispatcher = request.getRequestDispatcher(strViewPage); if (dispatcher != null){ dispatcher.forward(request, response); }

In MyServlet.java I have included,

String msg = (String)request.getAttribute("msg");

The problem is the values from JSP to servlet gives null values. I got msg=null.

Is there another way to get java variables from JSP tp servlet?

If there is some error in my code, please point that. Please give me your suggestions.
