The validation framework can handle different locales.
Here is an excerpt of the validation.xml file (I've
attached the full version). The xml file lets you
define your validation rules, define global constants,
locale constants, and a formset has country, language,
and variant just like locale. If you don't specify
any of these, it will use the default locale. You can
pass in variables with each locale, override the
default error message (message resource key), and have
parameters for the error message. The global constant
can be overridden by a locale level constant. So some
basic constants could be made for the most commonly
used locales or we could leave it up to the user and
just have examples.
<form-validation>
<global>
<constant name="zipPostal" value="^\d{5}\d*$" />
</global>
<formset>
<constant name="zipPostal"
value="^\d{5}(-\d{4})?$" />
<form name="profileForm">
<field property="firstName"
depends="required">
<arg0
key="profileForm.firstName.displayname"/>
</field>
<field property="zipPostal"
depends="required,mask">
<var name="mask" value="${zipPostal}"/>
<msg name="mask"
key="profileForm.zipPostal.maskmsg"/>
<arg0
key="profileForm.zipPostal.displayname"/>
</field>
</form>
</formset>
<formset language="fr" country="CA">
<constant name="zip" value="^\d{5}(-\d{4})?$" />
<form name="profileForm">
<field property="firstName"
depends="required">
<arg0
key="profileForm.firstName.displayname"/>
</field>
<field property="zipPostal"
depends="required,mask">
<var name="mask" value="${zipPostal}"/>
<msg name="mask"
key="profileForm.zipPostal.maskmsg"/>
<arg0
key="profileForm.zipPostal.displayname"/>
</field>
</form>
</formset>
</form-validation>
Everything is online at my site if you want to look at
it. The source, documentation, javadocs, and example
webapps are all available.
