今天搞了一天也不知道怎么验证不了我的代码：（如果不验证，代码是可以正确跳转的，加上验证就没反映了）如果看不懂我可以把源码给发过去
validation.xml<form-validation>
<formset>
<form name="loginForm">
<field property="userName" depends="required">
<arg0 key="form1.userName" />
</field>
</form>
</formset></form-validation>
ApplicationResource.properties如下form1.userName=用户名
form1.password=密码
form1.title=登陆
errors.required={0}不能为空
errors.minlength={0}长度不能小于{1} 个字符
errors.maxlength={0}不能大于{1} 个字符.上面的不知道有没有错我感觉是jsp页面有错如下：
<body>
<form name="form1" action="login.do">
<table align="center">
<tr><td colspan="2" align="center"><bean:message bundle="myKey" key="form1.title"/></td></tr>
<tr><td><bean:message bundle="myKey" key="form1.userName"/></td><td><input type="text" name="userName" size="18"></td><TD><html:errors property="userName"/></TD></tr>
<tr><td><bean:message bundle="myKey" key="form1.password"/></td><td> <input type="password" name="password" size="18"></td><TD><html:errors property="password"/></TD></tr>
<tr><td align="right"><input type="submit" value="提交"></td><td align="left"><input type="reset" value="重置"></td></tr>
</table>
</form>
是不是上面红色字体部分写的不对 </body>

LoginForm login=(LoginForm)form;
String name=login.getUserName();
HttpSession session=request.getSession();
String password=login.getPassword();
String forward="fail";
if(name.equals("zhangsan")&&password.equals("123456")){
forward="success";
session.setAttribute("username", name);
}
return mapping.findForward(forward);
如果我在登陆页面输入正确的字符串（zhangsan 123456）就显示这种提示

好几个这种类型的错误
在properties文件中userName找不到对应的值
errors.add("userName", new ActionMessage("errors.required"));
if(true){//判断
//TODO
}
//最后判断ActionErrors对象是否为空
if(!errors.isEmpty()){
return mapping.getInputForward();
}else{
//跳转成功页面
}
