HTTP Status 404 - Servlet is not available

[Christopher Meadows]

Hello

I'm a greenhorn, so any help is greatly appreciated. I setup a website using Netbeans 6.8 for our family business using jsp, servlets, and html. On the localhost, the website works with no issues. I recently uploaded to a webserver. The html pages work fine, but the servlets do not. I think I may have a problem with the web.xml file. I stored the servlets in public_html/WEB-INF/classes/controller.

Here is the web.xml file

I amended the xml file below.

Thanks

Please UseCodeTags.

Howdy Christopher,

Are you sure that info_FuneralServlet is the exact class name and you've packaged it to the "com.classes.controller" package? Comparing to the other classes in the controller package, I think it might be something like "controller.info_FuneralServlet "

[Bear Bibeault]

By the way, not following standard Java naming conventions makes your code surprisingly hard to read. "info_" is not a proper way to name a class.

[Christopher Meadows]

I'm sorry for improper CodeTag.

The xml file is located at public_html/WEB-INF
The servlets are located in public_html/WEB-INF/classes/controller
This an abbreviated xml file

    <servlet>
        <servlet-name>InfoServlet</servlet-name>
        <servlet-class>controller.InfoServlet</servlet-class>
    </servlet>
            <servlet-mapping>
        <servlet-name>InfoServlet</servlet-name>
        <url-pattern>/info</url-pattern>
    </servlet-mapping>
     

The website loads, but the servlet is blank.

Again: please UseCodeTags

So what URL are you browsing to?

Is the Servlet getting called? Can you please some System.out.println() statements into it and verify what is happening?
For that matter, are there any messages written to the application server's log file?

You're not telling us very much.

[Bear Bibeault]

Dumb question that must be asked. You wrote:

public_html is usually used by the Apache web server -- you are trying to run this in Tomcat or some other Servlet engine, right?

[Christopher Meadows]

Yes, I am running on with tomcat.

[Christopher Meadows]

The /index.html does call a servlet (InfoServlet) and does a quick query and displays the information to http://www.meadowsfuneralhomeinc.com/index.jsp. In the past, I would get an 404 error when the servlet was called. Now, I get a blank page.

[Bear Bibeault]

What's expected? Where's the servlet code. Don't make us pull teeth, give us more info.

Have you checked to see if the servlet is running at all? (logging comes in handy)

[Christopher Meadows]

Here is the servlet code

package controller;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import model.*;


public class InfoServlet extends HttpServlet {
   
    /** 
     * Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
     * @throws ServletException if a servlet-specific error occurs
     * @throws IOException if an I/O error occurs
     */
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();
        try {
            funeral_database search = new funeral_database();
            search.infoQuery();
            String resultsTable = search.infoHTMLTable();

            request.setAttribute("resultsTable", resultsTable);

            RequestDispatcher dispatcher = getServletContext().getRequestDispatcher("/index.jsp");
            dispatcher.forward(request,response);
        } finally { 
            out.close();
        }
    } 

    // <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
    /**

     */
    @Override
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    } 

    /**

     * @param request servlet request

     */
    @Override
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    }

    /** 
     * Returns a short description of the servlet.
     * @return a String containing servlet description
     */
    @Override
    public String getServletInfo() {
        return "Short description";
    }// </editor-fold>

}

I think I know what might be the problem, I changed the name on the database when I built it on the webserver. I will make the change in my code and compile. I will also reset my tomcat. I will try logging a messeage to see if my servlet is even working. Thank you for the advice. I will post my results.

[Christopher Meadows]

I checked the servlets by writing some test code and the servlets work. My problem must with the database connection. I will investigate further. I would like to thank everyone for their help.

Regards

Chris

I figured out the problem, I did not have Class.forName in my java file.

Class.forName("com.mysql.jdbc.Driver");

It was not required in Netbeans 6.8, thank for everyone's input.
