Running a servlet on Tomcat using Eclipse

[Raef Kandeel]

Hey guys! how is life. I was using Tomcat and Eclipse to run a servlet. Tomcat gave me the following error in response to this url: http://localhost:8080/FirstServlet/servlet/hall.SomeServlet:-

HTTP Status 404 - /FirstServlet/servlet/hall.SomeServlet

--------------------------------------------------------------------------------

type Status report

message /FirstServlet/servlet/hall.SomeServlet

description The requested resource (/FirstServlet/servlet/hall.SomeServlet) is not available.


--------------------------------------------------------------------------------

Apache Tomcat/6.0.14

I typed the url: http://localhost:8080/FirstServlet/servlet/hall.SomeServlet and it gave me the above error.

The three files that I had are:

ServerUtilities.java
---------------------

 [B]package hall;
 
public class ServerUtilities {
public static String  printHello () {
return ("hello");
}
}[/B]   

SomeServlet.java

[B]package hall;
 
import java.io.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
 
/**
 * Servlet implementation class for Servlet: SomeServlet
 *
 */
 public class SomeServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet {
   static final long serialVersionUID = 1L;
   
    /* (non-Java-doc)
 * @see javax.servlet.http.HttpServlet#HttpServlet()
 */
public SomeServlet() {
super();
}   

/* (non-Java-doc)
 * @see javax.servlet.http.HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
PrintWriter out= response.getWriter();
out.println ("<h1>" + ServerUtilities.printHello() + "WWW</h1>");
// TODO Auto-generated method stub
}  

/* (non-Java-doc)
 * @see javax.servlet.http.HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
 */
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
}         
}[/B]    

And my web.xml:-

    <servlet-name>SomeServlet</servlet-name>
    <servlet-class>hall/SomeServlet</servlet-class>
  </servlet>
  <servlet-mapping>
    <servlet-name>SomeServlet</servlet-name>
    <url-pattern>/hall.SomeServlet</url-pattern>
  </servlet-mapping>
</web-app>
  

Do you know what the problem might be. Thanks Ranchers.

I typed the url: http://localhost:8080/FirstServlet/servlet/hall.SomeServlet and it gave me the above error.

Take out the "servlet/" part of your url.
It isn't in your mapping so it shouldn't be in your URL.

[John Lu]

<servlet-class>hall/SomeServlet</servlet-class>

should be something like:

<servlet-class>hall.SomeServlet</servlet-class>
