    public void setUsername(String username)

        this.username = username;

==================
login.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
    pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

</head>
<body>
<form action="login.action" method="get" %>
用户名：<input type="text" name="username"><br/>
密码：<input type="password" name="password"><br/>
<input type="submit" value="login">
</form>

</body>
</html>

不管在login.jsp页面中输入的用户名是什么，都只会跳转到success.jsp页面。在LoginAction.java中打断点，没有作用，没有经过LoginAction.java中的execute方法的处理。
问题出在哪儿了？

------解决方案--------------------

楼主写代码不小心，execute方法名写错了，所以这个action里没有execute方法，自动返回success。。
