Webservlet突然停止工作

我有一个Webservlet（动态Web模块3.1），它看起来像这样：Webservlet突然停止工作

package de.timetoact.cce; 

import java.io.IOException; 
import java.net.MalformedURLException; 
import java.net.URISyntaxException; 

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

import com.ibm.sbt.services.client.ClientServicesException; 

import de.timetoact.cce.handler.ContentHandler; 
import de.timetoact.cce.util.Connect; 
import de.timetoact.cce.util.Util; 
import de.timetoact.cce.util.Variables; 

@WebServlet(urlPatterns = { "/main" }, loadOnStartup = 1) 
public class InitServlet extends HttpServlet { 

    private static final long serialVersionUID = 1L; 


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

     String actionn = request.getParameter("action").toLowerCase(); 
      if (actionn.equals("delete")) { 
       System.out.println("It does work"); 
      } 
    } 
}

web.xml中：

昨天它完美地工作，但今天我得到消息：

The requested resource is not available. /CCE/main

我打扫的项目，做了更新（Maven的更新项目）

不过，我得到了这个上下文错误，虽然我没有改变任何东西。

这里有什么问题？

此问题是由在eclipse或tomcat中运行项目的两个实例引起的。您可以通过重新启动eclipse或tomcat来解决此问题。
