Forwards a request from a servlet to another resource (servlet, JSP file, or HTML file) on the server.

Usage

From source file:DispatchServlet.java

public void doGet(HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException {

    // Forward to a display page
    String display = "/servlet/SearchView";
    RequestDispatcher dispatcher = req.getRequestDispatcher(display);
    dispatcher.forward(req, res);
}

From source file:MyServlet.java

public void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException, ServletException {
    ServletContext context = getServletContext();
    RequestDispatcher dispatcher = context.getRequestDispatcher("/myServlet");
    dispatcher.forward(req, res);
}

From source file:Main.java

protected void service(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    RequestDispatcher dispatcher = request.getRequestDispatcher("/p.jsp");

    dispatcher.forward(request, response);
}

 *
 * @param context The context that the error happened in (the JSP-defined pageContext, typically)
