hola,estoy desarrollando una aplicación web y cuando trato de validar tengo el siguiente problema:

org.apache.struts.validator.FieldChecks.validateRequired(java.lang.Object,
org.apache.commons.validator.ValidatorAction, org.apache.commons.validator.Field, org.apache.struts.action.ActionMessages,
javax.servlet.http.HttpServletRequest)

la version de struts 1.2.9 y tomcat 5.0 (ya he probado otras versiones y sigo con el mismo problema)

struts-config.xml:

...

<form-beans>
<form-bean name="loginForm"
type="org.apache.struts.validator.DynaValidatorForm">
<form-property name="loginName" type="java.lang.String"/>
<form-property name="password" type="java.lang.String"/>
<form-property name="rememberMyPassword" type="java.lang.Boolean"/>
</form-bean>
...
</form-beans>

...

<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
<set-property property="pathnames"
value="/WEB-INF/validator-rules.xml,
/WEB-INF/validation.xml"/>
</plug-in>
...


y el validation.xml es:

<formset>

<form name="loginForm">
<field property="loginName" depends="required">
<arg0 key="UserProfile.loginName"/>
</field>
<field property="password" depends="required">

<arg0 key="UserProfile.password"/>
</field>
</form>

...

</formset>

gracias por la molestia.
un saludo
