Cannot Invoke Servlets

[Ron Ingram]

I was working on a Web App project in NetBeans and I decided to move the location of my JSPs. I moved each JSP and remapped all of the links, however, it cannot invoke servlets even though the web.xml is correctly configured.

Is this a bug in Netbeans? I've tried changing web servers from tomcat to glassfish and same result.

I've attached the code for my servlet, the web.xml and link in jsp page. Basically, I'm trying to simply forward the user to another jsp page through a servlet. Please let me know any ideas or suggestions. Thanks, in advance.

package POAMServlets;

import javax.servlet.http.*;


public class NewPoam extends HttpServlet{

    public void processRequest(HttpServletRequest request, HttpServletResponse response, HttpSession session) throws Exception {

            //Forward to New Poam JSP
            //response.sendRedirect does not forward any information.  Use Dispatcher to forward headers
            response.sendRedirect("/NOS_ISSO/jsp/POAMnew.jsp");
    }

}

Here is the link I'm using in my JSP to invoke the NewPoam servlet:
<a href='NewPoam'>New POAM</a>

You need a servlet mapping, and your URL should start with the context path.

[Ron Ingram]

Thanks for the response. I thought anytime I create a servlet mapping in the web.xml file, I no longer need to add the context path, just simply name the servlet to match what is in the web.xml. Guess I was wrong as a newbie...

I added the 'context path/Servlet-name' and it works.

Remember that the form action is on the client. The browser has no knowledge of your mappings, so you must use the context path.
