怎么在struts里验证“确认密码”

在你的actionForm里有个validate方法，在里面将两个字段比较一下就可以了，如果不相同的话就返回一个ActionErrors对象（针对1.1,1.2里面好像使用ActionMessage代替了)，同时在struts-config.xml里将validate设置为true

出现这样的错误：
严重: com.ValidationUtil

validator-rules.xml里增加

    <validator name="twofields" classname="com.ValidationUtil" method="validateTwoFields" methodParams="java.lang.Object,

      <javascript>
        <![CDATA[ function validateTwoFields(form) {
            var bValid = true;
            var focusField = null;
            var i = 0;
            var fields = new Array();
            oTwoFields = new twofields();
            for (x in oTwoFields) {
                var field = form[oTwoFields[x][0]];
                var secondField = form[oTwoFields[x][2]("secondProperty")];                if (field.type == 'text' ||

                            focusField = field;

                        fields[i++] = oTwoFields[x][1];
                        bValid = false;

                focusField.focus();

            }            return bValid;
        }]]>
            </javascript>
    </validator>

validation.xml增加：
<var>
<var-name>secondProperty</var-name>
<var-value>conpwd</var-value>
</var>
