I want to open a popup window on calling a servlet and then want to redirect servlet to some .jsp page.

This is what i've done:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        PrintWriter out = response.getWriter();
        out.println("<html><body>");
        out.println("<script type=\"text/javascript\">");
        out.println("window.open(\"pageA.jsp\")");
        out.println("</script>");
        out.println("</body></html>");
        response.sendRedirect("pageB.jsp");
    }

This code will only popup window when the response.sendRedirect("error.jsp"); is not present or mented. Currently with this code, it is not popping a window and directly redirecting this page to error.jsp

How can i do both of the above things at the same time?

  • 1 You cannot use sendRedirect(), what that is used for is the client asked for A but the server says you really want B. What you are doing is returning A but in such a way that it loads B for that you need to use javascript or a meta tag. – BevynQ Commented Jan 3, 2013 at 20:43

Reset to default 1

You can use JavaScript do the trick. For example:

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    out.println("<html><body>");
    out.println("<script type=\"text/javascript\">");
    out.println("var popwin = window.open(\"pageA.jsp\")");
    out.println("setTimeout(function(){ popwin.close(); window.location.href='pageB.jsp';},5000)");
    out.println("</script>");
    out.println("</body></html>");
}

Instead of redirecting a page using sendRedirect, Use

window.location.href = 'pageB.jsp'

You can call a jsp page instead of servlet and canuse a jQuery plugin thickbox
