验证期间Struts2超时

Question

I get a TimeOut error when I try to validate my login form BUT only the first time. Could you tell me what I'm doing wrong?

My [...]-validation.xml :

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.2//EN" 
                            "http://struts.apache.org/dtds/xwork-validator-1.0.2.dtd">
<validators>
     <field name="identifiant">
         <field-validator type="requiredstring">
              <message>Veuillez saisir votre identifiant</message>
         </field-validator>
    </field>
    <field name="motDePasse">
         <field-validator type="requiredstring">
              <message>Veuillez saisir votre mot de passe</message>
         </field-validator>
    </field>
</validators>

The stackTrace :

Answer 1

The server was not able to access to Internet. So the DTD had to be copied and referenced locally.

Thanks to Roman C. for the clue.
