Passing java variables from JSP to Servlet - return null values
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.
