XML-RPC problem with jetty9

Welcome 

i have servlet and web.xml (show below) and i use jetty container to run it . but when i run jetty server dont read my project.
 
how can i solve this problem ?
 


servlet is ExampleService.java
 
//package example;
 
import java.util.Random;
 import java.util.HashMap;
 import javax.servlet.ServletConfig;
 import javax.servlet.ServletException;
 import redstone.xmlrpc.XmlRpcServlet;
 
public class ExampleService extends XmlRpcServlet
 {
 public void init( ServletConfig servletConfig ) throws ServletException
 {
 super.init( servletConfig );

 getXmlRpcServer().addInvocationHandler( "SimpleDatabase", new HashMap() );
 getXmlRpcServer().addInvocationHandler( "RandomNumberGenerator", new Random() );
 }
 }
 

and the web.xml is:

<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app> 

	<!-- To save as "hello\WEB-INF\web.xml" -->
	<servlet>
		<servlet-name>ExampleService</servlet-name>
		<servlet-class>ExampleService</servlet-class>
		<init-param>
			<param-name>streamMessages</param-name>
			<param-value>1</param-value>
		</init-param>
		<init-param> <!-- Optional! Defaults to text/xml and ISO-8859-1 -->
			<param-name>contentType</param-name>
			<param-value>text/xml; charset=ISO-8859-1</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>ExampleService</servlet-name>
		<url-pattern>/redstone</url-pattern>
	</servlet-mapping>

</web-app>

and the response from jetty server is:

2013-02-23 08:56:15.122:INFO:oejd.DeploymentManager:main: Deployable added: C:\Users\Nasser\jetty-distribution-9.0.0.RC0\webapps\redstone
