不能做一個簡單的HelloWorld碼頭webapp

我想在我的jetty v9.1中部署一個簡單的Helloworld webapp。我有當我試圖訪問servlet的問題，我recive的錯誤消息：不能做一個簡單的HelloWorld碼頭webapp

HTTP ERROR 404

問題存取/ HelloServlet /的servlet。原因：

Not Found

我知道我在這裏做錯了什麼，但我不知道是什麼。

這裏是Webbapp在碼頭我的文件結構：

的webapps

+例如

+你好

的hello.xml 的index.html + WEB-INF

的web.xml +類

HelloServlet.class

的index.html + WEB-INF（代表一個文件夾，WEB-INF和a index.html文件，在同一個文件夾你好）

這裏是我的web.xml

<?xml version="1.0" encoding="UTF-8"?> 
<web-app 
xmlns="http://java.sun.com/xml/ns/javaee" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" 
version="2.5"> 
<display-name>Example</display-name> 

<!-- Declaraa existenta unui servlet. --> 
<servlet> 
    <servlet-name>HelloServlet</servlet-name> 
    <servlet-class>HelloServlet</servlet-class> 

</servlet> 

<!-- Map URLs to that servlet. --> 
<servlet-mapping> 
    <servlet-name>servlet</servlet-name> 
    <url-pattern>/servlet</url-pattern> 
</servlet-mapping>

HelloServlet.java

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

public class HelloServlet extends HttpServlet { 

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException { 

    String input=request.getParameter("input"); 
    PrintWriter out=response.getWriter(); 

    out.println("<html>"); 
    out.println("<body>"); 
    out.println("The parameter input was \" "+input+"\" ."); 
    out.println("</body"); 
    out.println("</html"); 

} 


protected void doPost(HttpServletRequest request,HttpServletResponse response) throws IOException { 

    String field=request.getParameter("field"); 
    PrintWriter out=response.getWriter(); 

    out.println("<html>"); 
    out.println("<body>"); 
    out.println("You entered \" "+field+"\" into the text box."); 
    out.println("</body>"); 
    out.println("</html>"); 

} 

}

的index.html

<html> 
<head> 
    <title>Example Web Application</title> 
</head> 

<body> 
    <p>This is a static document with a form in it.</p> 
    <form method="POST" action="servlet"> 
     <input name="field" type="text" /> 
     <input type="submit" value="Submit" /> 
    </form> 
</body> 
</html>
