redirect jsp from servlet RequestDispatcher

Question

I want to redirect JSP page from one servlet. All JSP pages are under Web Content. not under Web-INF. I have a problem of calling that JSP pages.

Answer 1

This error occurs when you have an error in java scriptlet of your jsp you've forwarded your request to.
For example I was calling <% request.getAttribute("user"); %> whereas the problem solved when I used <% request.getParameter("user") %>

Answer 2

A slightly cleaner way to write this code is:

request.getRequestDispatcher("/thankyou.jsp").forward(request, response);

Answer 3

I solved the problem using RequestDispatcher like this:

RequestDispatcher requestDispatcher; 
requestDispatcher = request.getRequestDispatcher("/thankYou.jsp");
requestDispatcher.forward(request, response);

Answer 4

Better way to use 'sendRedirect()' method using response object.

you can write like

 response.sendRedirect("./newpage.jsp");

This will send control to your 'newpage.jsp' page.

Answer 5

Use SendDirect if you want to work with JSP pages

response.sendRedirect("/thankyou.jsp");

This is simpe thing to use than RequestDispatcher which doesn't work with doPost().
