[validator] Resource bundle with standalone validation

[Ben Avery <be...@youthnetuk.org>]

I want to use a resource bundle to generate meaningful error messages, 
using Validator in a standalone, non-Struts environment.

What do I need to put in the Java class which instantiates and calls the 
Validator, so it understands which resourcebundle file to look up 
references like

xml config file:
...
<global>
     <validator
       name="email"
       classname="org.youthnet.ben.ValidatorWrapper"
       method="doValidEmail"
       methodParams="java.lang.Object, org.apache.commons.validator.Field"
       msg="errors.email"/>
...
</global>

<formset>
   <form name="simpleform">
      <field property="startDate" depends="required">
         <arg position="0" key="Start date"/>
      </field>
...
   </form>
</formset>
...

the resource file would look like:

errors.required={0} is required.
errors.maxlength={0} cannot be greater than {1} characters.
errors.email={0} is an invalid email address.

There is a good discussion of that on the Commons-Validator site.   If 
you're in a web environment you basically initilalize your resource 
bundle in an initialization servlet.  Check out this link. 
http://wiki.apache.org/jakarta-commons/ValidatorStandalone.  If you need 
an example of the code I can send you what I've done.  If you're outside 
the web environment there are a few other things that you can do, but I 
will let others speak on that as I have not done that.

Thanks,

Matt
