<title>JSP for LoginForm form </title>

<body>
<html:form action="/login">
password : <html:password property="password"/> <br/>
username : <html:text property="username"/> <br/>
<html:submit/> <html:cancel/>
</html:form>
</body>
</html>
但是却出现了这样的错误，不知道是不是标记的问题？需要导入什么包的吗？

网友回复: <html:text property="username"/>
这个似乎是有问题
好久没有用过struts1.2了
网友回复:1.標籤寫錯
2.bean裡面get的方法沒有
另外不懂你要干什麽。。。
网友回复:在LoginForm这个类里面必须有
setUsername(),getUsername(),setPassword()和getPassword()这四个方法,并且方法名和返回值不能写错
你再检查一下,建议用工具自动生成setter和getter这样不会出错
网友回复:我的全部都是自动生成的，什么也没有改动过，就错了
网友回复:form 中的getXXX() setXXX()方法没写或名字写错了吧？
网友回复:你的actionform里面的属性和你表单的属性不一样。。找不到那个方法。。。加分。。。绝对正确
