参考：《JavaServer Faces核心编程(第3版)》

User

import javax.faces.bean.ManagedBean;

@ManagedBean(name="user")或者@Named("user")
@SessionScoped
public class User {
private String name="";
private String password="";
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

JSF2.0之前需要在WEB-INF/faces-config.xml文件中生命bean，对于一个简单应用程序其实不需要faces-config.xml配置文件
