我正在使用Struts 2單選按鈕。 我想從我的動作類檢索列表中，但它給下面的錯誤Struts 2單選按鈕列表
org.apache.jasper.JasperException：標籤 「無線電」，字段「列表」，名稱 「user.yourGender」：請求列表 鍵'＃user.gender'不能爲 解析爲 集合/數組/映射/枚舉/迭代器 類型。例：人或人{名} - [未知地點]
我的動作類&用戶類是遵循
HelloAction
package com.geekcap.struts2.action;
import com.geekcap.struts2.model.User;
import com.opensymphony.xwork2.ActionSupport;
import java.util.List;

{
private User user;
public String execute() throws Exception
{
return "success";
}
public void validate()
{
if(user.getName().length()==0)
{
addFieldError("user.name", "User Name is required");
}
if(user.getAge()==0)
{
addFieldError("user.age","Age is required");
}
if(user.getPassword().length()==0)
{
addFieldError("user.password","Please enter your password !");
}
/* if(user.getGender().equals("-1"))

這將是有益的，如果你可以格式化你的問題更好地[提示：使用「代碼」格式化。你用於單選按鈕的html代碼是什麼？作爲anirvan的 – anirvan 2010-12-14 07:27:50
表示使用代碼格式化程序按鈕（標記爲1010的那個）來格式化代碼。這次我爲你做了。 – Nivas 2010-12-14 07:53:20
