Hi, Yoav:
Thank you for your help. Would you mind tell me how to
ualEncode the my second servlet URL in the javascript.
public void service(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException
{
try {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<SCRIPT
LANGUAGE=\"JavaScript\">");
out.println("function
loadcheckmodificationservlet()");
out.println("{");
out.println("document.location=\"CheckURL1&myReferer=test\";");
out.println("}");
out.println("</script>");
out.println("</head>");
out.println("<body bgcolor=\"white\">");
out.println("<body>");
out.println("<h1>" + "test" + "</h1>");
out.println("<font color=\"#3333FF\"><a
href=\"CheckURL1\">Pending Reviews</a></font></li>");
out.println("<p><b><font color=\"#3333FF\"><a
href=\"javascript:loadcheckmodificationservlet();\">Modify
Audit</a></font></b>");
out.println("</body>");
out.println("</html>");
}
Thanks a lot.
