Form Validator java.lang.InstantiationException

[Cyrille37]

Hello,

I'm trying to create a really simple Form field validator but it fails 
and throw an java.lang.InstantiationException.
Since 3 hours I'm looking in TAP's severals examples but I could not 
find the reason of the exception.
Please could you help me to find where is my error ?
Thanks
Cyrille

Here is my files :

**in hivemodule.xml :**

<contribution configuration-id="tapestry.form.validator.Validators">
<validator
 class="tap03.ui.web.validators.DocumentsUploadFileValidator"
 name="documentsUploadFileValidator"
 configurable="false"
/>
</contribution>

**in the html page :**

<td><span jwcid="@FieldLabel" field="component:inputFile"/>:</td>
<td><input jwcid="[EMAIL PROTECTED]" file="ognl:file" size="30" 
displayName="File" validators="validators:documentsUploadFileValidator"/>
</td>

**the java file :**

package tap03.ui.web.validators;

import org.apache.tapestry.form.IFormComponent;
import org.apache.tapestry.form.ValidationMessages;
import org.apache.tapestry.form.validator.BaseValidator;
import org.apache.tapestry.valid.ValidatorException;

public abstract class DocumentsUploadFileValidator extends BaseValidator
{
   public DocumentsUploadFileValidator()
   {
       
System.err.println("DocumentsUploadFileValidator.DocumentsUploadFileValidator()");
   }

   public DocumentsUploadFileValidator(String initializer)
   {
       super(initializer);
       
System.err.println("DocumentsUploadFileValidator.DocumentsUploadFileValidator(String 
initializer)");
   }

   public void validate(IFormComponent field, ValidationMessages 
messages, Object object) throws ValidatorException
   {
       System.out.println("DocumentsUploadFileValidator.validate()");
   }
}
