struts2 + jquery + json 出现问题

出现java.lang.NoSuchMethodException setUser([LJava.lang.String;)异常； action部分代码：

public class UserAction{
private User user;
private String name;
public void setName(String name){
this.name = name;


}
public String getName(){
return name;
}
public User getUser() {
      return user;
}


public void setUser(User user) {
      this.user = user;
}

public String execute(){
     System.println(user.getUsername);
}

}

User就两个属性：username/password.

struts.xml:

<package name="json" extends="json-default">
     <action name="save" class="com.aaron.example.action.UserAction">
	<result type="json"></result>
     </action>
</package>

jQuery代码：

$(function(){
     var json = {"user":{"username":"zhangsan","password":"123"}};//方法1
 

     //json = {"name":"zhanglong"};// 方法2
 

     //json = {"user.username":"zhangsan","user.password":123};//方法3
     $.post("save.action", json);
});

用方法1会出项上述错误，方法2和方法3都可行，谁能为我解忧，感激不尽！

哎，居然没人回答，还是要靠自己。我把解决方法放在BlogJava上了。
