    Custom validator - ClassNotFoundException

    Alex Cougarman Apprentice

      I'm trying to create a custom validator for a Seam app, but it keeps throwing an exception saying:

      The validator's code is this:



      package org.unctv.metaform.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-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 not valid");
                  message.setSummary("Email not valid");
                  message.setSeverity(FacesMessage.SEVERITY_ERROR);
                  throw new ValidatorException(message);
              }
           }
      }





      The faces-config file has this:


      <validator>
        <validator-id>EmailValidator</validator-id>
        <validator-class>org.unctv.metaform.session.EmailValidator</validator-class>
       </validator>



      The xhtml page has this:


      <h:inputText id="txtEmail" value="#{asset.email}"
      validatorMessage="Email is not valid." required="true">
      <f:validator validatorId="EmailValidator"/>
      </h:inputText>



      What am I doing wrong?
