java - 验证期间Struts2超时

Question

当我第一次尝试验证我的登录表单时，我收到超时错误。你能告诉我我做错了什么吗？

我的 [...]-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>

服务器无法访问 Internet。因此必须在本地复制和引用 DTD。
