关于struts自定义validator的问题(70分)

各位老大,帮我解决一下关于struts自定义validator的问题
自定义validator出错！！
那位老大可以帮小弟看看哪里错了~~
在JSP上
<html:errors/>
<html:form action=&quot;myAction.do&quot;
focus=&quot;myForm&quot;
>
用户名：<html:text property=&quot;name&quot;
/><br>
EMail：<html:text property=&quot;mail&quot;
/><br>
生日：<html:text property=&quot;birthday&quot;
/><br>
密码：<html:text property=&quot;password&quot;
/><br>
验证密码：<html:text property=&quot;password2&quot;
/><br>
<html:submit>
<bean:message key=&quot;btn.save&quot;/>
</html:submit>
</html:form>
以下是ActionForm
public class MyForm extends ValidatorForm {
private String name;
private String mail;
private String birthday;
private String password;
private String password2;
......
}
自定义validator
public class MyValidator implements Serializable {
public static boolean validateTwofields(Object bean,
ValidatorAction va, Field field,
ActionMessages errors,
HttpServletRequest request) {
String value = ValidatorUtils.getValueAsString(bean, field.getProperty());
String sProperty2 = field.getVarValue(&quot;secondProperty&quot;
String value2 = ValidatorUtils.getValueAsString(bean, sProperty2);
if (!GenericValidator.isBlankOrNull(value) &&
!GenericValidator.isBlankOrNull(value2)) {
try {
if (!value.equals(value2)) {
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
}
} catch (Exception e) {
errors.add(field.getKey(),
Resources.getActionMessage(request, va, field));
}
} else
{
errors.add(field.getKey(),
Resources.getActionMessage(request, va,
field));
}
return errors.isEmpty();
}
}
validator-rules.xml中加
<!--myvalidator-->
<validator name=&quot;twofields&quot;
classname=&quot;validatortest.MyValidator&quot;
method=&quot;validateTwofields&quot;
methodParams=&quot;java.lang.Object,
org.apache.commons.validator.ValidatorAction,
org.apache.commons.validator.Field,
org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest&quot;
depends=&quot;required&quot;
msg=&quot;errors.twofields&quot;
/>
validation.xml中加
<formset>
<form name=&quot;myForm&quot;>
<field property=&quot;name&quot;
depends=&quot;required,minlength,maxlength&quot;>
<arg0 key=&quot;name&quot;
resource=&quot;false&quot;/>
<arg1 key=&quot;minLength&quot;
name=&quot;${var:minlength}&quot;
resource=&quot;false&quot;/>
<arg1 key=&quot;maxLength&quot;
name=&quot;${var:maxlength}&quot;
resource=&quot;false&quot;/>
<var>
<var-name>minlength</var-name>
<var-value>4</var-value>
</var>
<var>
<var-name>maxlength</var-name>
<var-value>20</var-value>
</var>
</field>
<field property=&quot;mail&quot;
depends=&quot;required,email&quot;>
<arg0 key=&quot;mail&quot;
resource=&quot;false&quot;/>
</field>
<field property=&quot;birthday&quot;
depends=&quot;required,date&quot;>
<arg0 key=&quot;birthday&quot;
resource=&quot;false&quot;/>
</field>
<field property=&quot;password&quot;
depends=&quot;required,twofields&quot;>
<arg0 key=&quot;password&quot;
resource=&quot;false&quot;/>
<var>
<var-name>secondProperty</var-name>
<var-value>password2</var-value>
</var>
</field>
<field property=&quot;password&quot;
depends=&quot;required,twofields&quot;>
<arg0 key=&quot;password&quot;
resource=&quot;false&quot;/>
<var>
<var-name>secondProperty</var-name>
<var-value>password2</var-value>
</var>
</field>
</form>
</formset>
