Struts1.0的validation无法验证日期有效性，大家帮帮忙？

Question

validation.xml(设定内容)
<field property="ymd" depends="required,minlength,maxlength,date">
<arg key="YoshinbiIkkatsu.yoshinym.0001" />
<msg name="required" key="error.10001" />
                <var>
                      <var-name>minlength</var-name>
                      <var-value>8</var-value>
                </var>
                <msg name="minlength" key="error.10026" />
                <arg key="YoshinbiIkkatsu.yoshinym.0001" />                
                <var>
                      <var-name>maxlength</var-name>
                      <var-value>8</var-value>
                </var>
                <msg name="maxlength" key="error.10026" />
                <arg key="YoshinbiIkkatsu.yoshinym.0001" />            
                <var>
     <var-name>datePatternStrict</var-name>
     <var-value>yyyyMMdd</var-value>
    </var>
    <msg name="date" key="error.10027" />
                <arg key="YoshinbiIkkatsu.yoshinym.0001"/>
            </field>页面中，输入"2011041a".只有这种最后一位是字母的时候无法验证。为什么呢？

Answer 2

网上下载checkDate.js;用js进行验证。日期格式是yyyy-mm-dd

Answer 3

可是为什么Validation不好用的？Strut的Bug？

Answer 4

一般时间不都是用js控件输入，我不知道lz要验证干嘛，多此一举啊
