Validation d'un formulaire dynamique

Bonjour,

J'ai un problème dans la validation d'un formulaire, dans mon fichier struts-config.xml j'ai le formulaire suivant:

Code:

1
2
3
4
5
6
7
	<form-beans>
   	 <!-- Si nous validons de forme dynamique le formulaire, alors nous n’avons pas besoin de crée les les clase qui dérive de ActionForm. -->
   	 <form-bean name="loginForm" type="org.apache.struts.validator.DynaValidatorForm">
		<form-property name="nombre" type="java.lang.String"></form-property>
		<form-property name="password" type="java.lang.String"></form-property>
	 </form-bean>
	</form-beans>

et aussi la localisation des fichier de validation:

Code:

1
2
3
4
 
<plug-in className="org.apache.struts.validator.ValidatorPlugIn">
		<set-property property="pathnames" 	value="/WEB-INF/validator-rules.xml,/WEB-INF/validation.xml" />
	</plug-in>

voici le contenu du fichier validation.xml en relation avec ce formulaire:

Code:

1

<form-validation>
	<formset>
		<form name="loginForm">
			<field property="nombre"  depends="required, minlength, maxlength">
				<arg0 key="label.nombre" />
				<arg1 name="minlength" key="${var:minlength}" resource="false"/>
				<arg2 name="maxlength" key="${var:maxlength}" resource="false"/>
				<var>
					<var-name>minlength</var-name>
					<var-value>3</var-value>
				</var>
				<var>
					<var-name>maxlength</var-name>
					<var-value>50</var-value>
				</var>
			</field>
 
			<field property="password" 	depends="required, minlength,maxlength">
				<arg0 key="label.password" />
				<arg1 name="minlength" key="${var:minlength}" resource="false" />
				<arg2 name="maxlength" key="${var:maxlength}" resource="false" />
				<var>
					<var-name>minlength</var-name>
					<var-value>3</var-value>
				</var>
				<var>
					<var-name>maxlength</var-name>
					<var-value>30</var-value>
				</var>
			</field>
 
		</form>
	</formset>
</form-validation>

dans ma classe qui a pour but de faire des opérations sur ce formulaire j'ai:

Code:

1
2
3
DynaValidatorForm myform = (DynaValidatorForm) form;
		System.out.println("Nom: " + myform.get("nombre"));
		System.out.println("Prénom :" + myform.get("password"));

je pensais avoir tout bien défini, mais j'ai un jolie message d'erreur:
