大伙帮帮忙 struts的validator问题
validation.xml 内容如下
<formset>
<form name= "registerForm ">
<field property= "name "
depends= "required,minlength ">
<arg0 key= "registrationForm.firstname.displayname "/>
<arg1 name= "minlength " key= "${var:minlength} " resource= "false "/>
<var>
<var-name> minlength </var-name>
<var-value> 5 </var-value>
</var>
</field>
<field property= "email "
depends= "required,email "
page= "2 ">
<arg0 key= "registrationForm.email.displayname "/>
</field>
</form>
</formset>
属性文件加入了相应的KEY,struts文件也做了相当的配置.当执行form的validate方法时就报以下错误.

[解决办法]
是不是rules文件的問題
[解决办法]
建议你看一下tomcat的日志
那有明确的错误记录
