JSF Validator not found

I have created a validator in my project in the package "com.travstar.validators" called EmailValidator.

Content of the class:

package com.travstar.validators;

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.FacesValidator;
import javax.faces.validator.Validator;
import javax.faces.validator.ValidatorException;

@FacesValidator("emailValidator")
public class EmailValidator implements Validator
{
    private static final String EMAIL_PATTERN = "^[_A-Za-z0-9-]+(\\." +
            "[_A-Za-z0-9-]+)*@[A-Za-z0-9]+(\\.[A-Za-z0-9]+)*" +
            "(\\.[A-Za-z]{2,})$";

    private Pattern pattern;
    private Matcher matcher;

    public EmailValidator()
    {
        pattern = Pattern.compile(EMAIL_PATTERN);
    }

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException
    {

        matcher = pattern.matcher(value.toString());
        if (!matcher.matches())
        {

            FacesMessage msg = new FacesMessage("Email validation failed.", "Invalid Email format.");
            msg.setSeverity(FacesMessage.SEVERITY_ERROR);
            throw new ValidatorException(msg);
        }
    }
}

and I implement the email validation like this: 

<h:panelGrid columns="1" width="100%">
                    <h:outputText value="Email Address"></h:outputText>
                    <h:inputText id="emailAddress" value="#{passengerDetailsBean.contactDetails.emailAddress}" styleClass="input-block-level" placeholder="" required="true">
                        <f:validator validatorId="emailValidator"></f:validator>
                    </h:inputText>
                    <h:message for="emailAddress" styleClass="alert alert-error" />
                </h:panelGrid>

This is more or less exactly like a tutorial I found online, but I haven't been able to get it working.

The moment I hit the page, the following exception is thrown:

javax.servlet.ServletException: Unknown validator id 'emailValidator'

I'm using JSF 2.1, so as far as I know I am not required to fiddle with the faces.config.xml

Anyone have any ideas as to why this is happening?

Apparently the target server is agressively caching its deploy/work folder and not immediately noticing any external changes. Which one are you using? Does it have kind of "development" and "production" stage setting? Set it to development.
