    FacesException: Named object not found

    Alex Cougarman Apprentice

      I'm trying to fix an error that keeps popping up with my Seam apps. The apps try to reference a non-Seam class file that contains this:


      package forms.session;
      
      import java.util.regex.Matcher;
      import java.util.regex.Pattern;
      
      import javax.faces.application.FacesMessage;
      import javax.faces.component.UIComponent;
      import javax.faces.context.FacesContext;
      import javax.faces.validator.Validator;
      import javax.faces.validator.ValidatorException;
      
      public class EmailValidator implements Validator{
              public EmailValidator(){}
              
              public void validate(FacesContext context, UIComponent component, Object obj)
                              throws ValidatorException {
                      // TODO Auto-generated method stub
                      String enteredEmail = (String)obj;
              //Set the email pattern string
              Pattern p = Pattern.compile("^(?:[a-zA-Z0-9_'^&/+-])+(?:\\.(?:[a-zA-Z0-9_'^&/+-])+)*@(?:(?:\\[?(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?))\\.){3}(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\]?)|(?:[a-zA-Z0-9-]+\\.)+(?:[a-zA-Z]){2,}\\.?)$"); //(".+@.+\\.[a-z]+"); 
              
              //Match the given string with the pattern
              Matcher m = p.matcher(enteredEmail);
              
              //Check whether match is found
              boolean matchFound = m.matches();
              
              if (!matchFound) {
                  FacesMessage message = new FacesMessage();
                  message.setDetail("Email is not valid.");
                  message.setSummary("Email is not valid.");
                  message.setSeverity(FacesMessage.SEVERITY_ERROR);
                  throw new ValidatorException(message);
              }
              }
      }



      The faces-config.xml has the following:


      <validator>
        <validator-id>EmailValidator</validator-id>
        <validator-class>forms.session.EmailValidator</validator-class>
       </validator>



      The XHTML page has this:


      <h:inputText id="txtRequestorEmail" value="#{employee.requestorEmail}"
        required="true" requiredMessage="Requestors Email is required."
        maxlength="50" >
        <f:validator validatorId="EmailValidator"/>
      </h:inputText>



      I've tried putting the class file for the EmailValidator into a JAR file and including in the project, but it makes no difference. It throws this exception:


      javax.faces.FacesException: Expression Error: Named Object: EmailValidator not found.

      What am I doing wrong? How do I tell Seam/JSF to see the non-Seam class?
