Solution

  • i don't know about GlassFish Server,but tomcat. A JSP file under WEB-INF folder can't be visit by URL directly,you can visit it like this:

    request.getRequestDispatcher(“/WEB-INF/xxx.jsp”).forward(request,response);

    I'm not sure this way can solve the question under GlassFish,hope it can help you.
