Невозможно загрузить аннотированный класс: validators.EmailValidator, вызванный java.lang.ClassNotFoundException: validators.EmailValidator

Question

Я пытаюсь реализовать пользовательский валидатор, как показано ниже. Это то, что появляется в моем классе EmailValidator.java который находится внутри пакета валидаторов:

package validators; 

import javax.faces.application.FacesMessage; 
import javax.faces.component.UIComponent; 
import javax.faces.context.FacesContext; 
import javax.faces.validator.FacesValidator; 
import javax.faces.validator.Validator; 
import javax.faces.validator.ValidatorException; 
import javax.mail.internet.AddressException; 
import javax.mail.internet.InternetAddress; 

@FacesValidator("validators.EmailValidator") 
public class EmailValidator implements Validator { 

    private static boolean isValidEmailAddress(String email) { 
     boolean result = true; 
     try { 
      InternetAddress emailAddr = new InternetAddress(email); 
      emailAddr.validate(); 
     } catch (AddressException ex) { 
      result = false; 
     } 
     return result; 
    } 

    /** 
    * 
    * @param context 
    * @param component 
    * @param value 
    */ 
    @Override 
    public void validate(FacesContext context, 
         UIComponent component, 
         Object value) throws ValidatorException { 
     try { 
      String emailAddress = (String)value; 

      if (!isValidEmailAddress(emailAddress)) { 
       FacesMessage message = new FacesMessage("Email address format is not valid."); 
       throw new ValidatorException(message); 
      } 

     } catch (ClassCastException e) { 
      FacesMessage message = new FacesMessage("Value must be a a String."); 
      throw new ValidatorException(message); 
     } 

    } 

} 

Это является частью моей страницы JSP, которая использует этот валидатор:

<b:inputText id="email" placeholder="Email" required="true" requiredMessage="Value is required" value="#{createAccountBean.email}"> 
     <f:validator validatorId="validators.EmailValidator" /> 
</b:inputText> 
<h:message id="emailMsg" style="color: red" for="email" /> 

Но это ошибка сервера GlassFish дает мне:

Я не уверен, что я делаю неправильно. Любые намеки будут оценены.
