How to send redirect to JSP page in Servlet

Question

When I'm done processing in a servlet, and the result is valid, then I need to redirect the response to another JSP page, say welcome.jsp in web content folder. How can I do it?

For example:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {     try {           // Some processing code here ...           // How do I redirect to another JSP here when I'm ready?      } catch (Exception e) {         throw new ServletException(e);     } }

Look at the HttpServletResponse#sendRedirect(String location) method.

Use it as:

response.sendRedirect(request.getContextPath() + "/welcome.jsp") 

Alternatively, look at HttpServletResponse#setHeader(String name, String value) method.

The redirection is set by adding the location header:

response.setHeader("Location", request.getContextPath() + "/welcome.jsp");
