關於servlet的錯誤，同時部署

-1

我已經開發了一個簡單的servlet，通過在Eclipse中選擇dynamci項目顯示below..in日食...關於servlet的錯誤，同時部署

的servlet ..

package com.demo; 

import java.io.IOException; 
import java.io.PrintWriter; 

import javax.servlet.ServletException; 
import javax.servlet.annotation.WebServlet; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

    public class Myservlet2 extends HttpServlet { 
     private static final long serialVersionUID = 1L; 


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

      System.out.println("Servlet 2 of App2 invoked..."); 
      response.setContentType("text/html"); 
      PrintWriter out=response.getWriter(); 
      out.println("This output is generated by servlet2 of app2"); 
      out.close(); 

     } 
    }

和網絡。 XML是...

<servlet> 
<servlet-name>Myservlet2</servlet-name> 
<servlet-class>com.demo.Myservlet2</servlet-class> 
</servlet> 
<servlet-mapping> 
<servlet-name>Myservlet2</servlet-name> 
<url-pattern>/servlet2</url-pattern> 
</servlet-mapping>

在通過月食，我得到了下面的錯誤在Tomcat中部署它..

這是更好，如果你開始閱讀一些好的教程庫罐子。在發佈的所有四個問題中，您的錯誤類型幾乎相同 – 2012-07-16 07:25:59

檢查類com.demo.MyServlet2存在於WEB-INF/classes或位於WEB-INF/lib
