正文内容：在学习webwork中想作一个用用户登录验证的例子，验证时能够按xwork中的设置出现提示信息，但是一直想要的在客 户端产生javascript提示，真是令人费解。按xiaxin的学习文档moxie的文档反复作了几遍，都不行。
这是源码：一个 action,二个jsp页面，一个 validation.xml文件，xwork.xml
package com.mystore;
import com.opensymphony.xwork.actionsupport;
public class loginaction extends actionsupport {
private user user = new user();
public user getuser() {
return user;
}
public void setuser(user user) {
this.user = user;
}
public string execute() throws exception {
// todo auto-generated method stub
return success;
}
}
input.jsp
<%@taglib prefix="ww" uri="webwork"%>
<html>
<head>
<base href="<%=basepath%>">
<title>my jsp input.jsp starting page</title>
</head>
<body>
</body>
</html>
result.jsp
<%@taglib prefix="ww" uri="webwork"%>
<html>
<head>hi,the result of validation</head>
<body>
this is my jsp page.
