Java Servlet, Send a redirect with html tags

Issue

I'm looking for a way to send a redirection with my servlet from my first page to a second page adding into the second page a script tag made inside this servlet.

For example:

protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    System.out.println("Received a get request");
    response.getWriter().append("<script>alert(\"I'm here!\")</script>");
    response.sendRedirect("testRedirect.html");
}

This code doesn't work. How can I fix it? Thanks!

Solution

Thank for your answers I solved with this code:

protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
    System.out.println("received a get message");
    PrintWriter out = response.getWriter();
    out.println("<script>alert(\"I'm here\");</script>");
    request.getRequestDispatcher("testRedirect.html").include(request, response);
    out.close();
}
