我今天试了试struts2声明式表单验证，可是没有错误信息回显。是我的哪里错误了呢？谢谢大家帮忙。
命令台输出了这样的信息：
2010-5-24 9:50:34 com.opensymphony.xwork2.util.logging.commons.CommonsLogger error
严重: Validation error for age:年龄必须在13-20
感觉验证是执行了，可是我的form_validation.jsp页面没有显示验证错误的信息。
我的配置如下：
//ValidationAction.java
public class ValidationAction {
private String msg;
private int age;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String execute() {
return "success";
}
}
//form_validation.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@ taglib prefix="s" uri="/struts-tags" %>
