Java 404在cloudbees上运行基本servlet时出错

我提到cloudbee的原因是为了确保没有特殊的设置需要我改变

这是我的测试代码，以确保它正常工作

package test;

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;

/**
 * Servlet implementation class testing
 */
@WebServlet("/testing")
public class testing extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**i
     * @see HttpServlet#HttpServlet()
     */
    public testing() {
        super();
        // TODO Auto-generated constructor stub
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        PrintWriter out = response.getWriter();
        out.println("test");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */`enter code here`
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
    }

}

它在本地tomcat7上工作…但是当我通过.war文件将它上传到Cloudbees时，我得到了404错误

我试着用Java6导出，有/没有对Tomcat7进行优化，因为cloudbees做了tomcat6

还有什么我不知道的地方吗？

我知道了

由于某些原因，未创建默认的web.xml文件。根本不在那里。奇怪
