java Maven+JSF 2+Google AppEngine:404错误

2 周，1 日 Questions & Answers 657

我试图在appengine开发服务器上运行一个带有jsf的maven项目，对于每个托管bean，我都会得到一个404错误（未找到）。我编辑了来自http://www.mkyong.com/jsf2/jsf-2-0-hello-world-example/的文件以与GAE合作。以下是修改后的文件：

你好。爪哇

package com.mkyong.common;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
import java.io.Serializable;

@ManagedBean
@RequestScoped
public class HelloBean implements Serializable {
 public String getName() {
  return "abc";
 }
}
