打开不了servlet

[Alan_TW]

最近在学习android连接服务器，前几天还好好的，今天突然出现了404错误。代码如下：
package login;
import java.io.IOException;
import java.io.PrintWriter;
import java.util.HashMap;
import java.util.Map;

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

import dao.UserItem;

public class AndroidLogin extends HttpServlet {
public AndroidLogin() {
super();
}
public void destroy() {
super.destroy(); // Just puts "destroy" string in log
// Put your code here
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
Boolean flag = false;
int phoneNumber = Integer.valueOf(request.getParameter("phoneNumber")); //获得电话号码
String Password = request.getParameter("Password"); //获得密码
if(UserItem.IfPassword(phoneNumber, Password))
{
flag = true;
}
else {flag = false;}
out.print(flag);
out.flush();
out.close();
}

/**
* Initialization of the servlet. <br>
*
* @throws ServletException if an error occurs
*/
public void init() throws ServletException {
// Put your code here
}
}
web.xml文件中的代码如下：
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
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">
<servlet>
<description>This is the description of my J2EE component</description>
<display-name>This is the display name of my J2EE component</display-name>
<servlet-name>AndroidLogin</servlet-name>
<servlet-class>login.AndroidLogin</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>AndroidLogin</servlet-name>
<url-pattern>/login/AndroidLogin</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
工程也发布了，打开index.jsp也没有问题；但是打开AndroidLogin就有问题了。输入的地址是：http://127.0.0.1:8888/AndroidLogin/login/AndoirdLogin?phoneNumber=123&Password=123,望大神指导一下。

服务端是用tomcat部署的吗？是的话，把tomcat中的work\Catalina\localhost目录下的AndroidLogin目录删掉试试

[Alan_TW]

我刚试了，还是不行，烦死我了

[Alan_TW]

把tomcat中的work\Catalina\localhost目录下的AndroidLogin目录删掉是可行的，我开始没有重启，重启服务器后是可以执行的。有时jsp也会遇见这种问题，好像是服务器编译的问题
