Scope in JSF Validator

I want to implement input validation. This is the managed bean code:

This is the code I added in faces-config.xml

<validator>
    <validator-id>ValidatorController</validator-id>
    <validator-class>com.DX_57.HM_57.FormValidator</validator-class>
</validator>

This is the verification code I tried to verify:

import javax.enterprise.context.SessionScoped;
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;
import javax.inject.Named;

@Named("ValidatorController")
@SessionScoped
public class FormValidator implements Validator {

    public FormValidator() {
    }

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        throw new UnsupportedOperationException("Not supported yet.");
    }

    public void validateMessage(FacesContext context, UIComponent component, Object value) throws ValidatorException {

        if (value.equals("test")) {
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
                    "Session ID is already in use, please choose another.", null));
        }
    }
}

The problem is this error that I get when I try to run the example:

It seems that the Validator class is not in the right area. What area should I use?

Best regards

Check this code:

<h:panelGroup>Session ID</h:panelGroup>
<h:panelGroup>
    <h:inputText id="sessionid" value="#{DatabaseController.formMap['sessionid']}" 
                    validator="#{ValidatorController.validatebean}">                                        
        <f:ajax event="blur" render="sessionidMessage" />                                          
    </h:inputText>
    <h:message id="sessionidMessage" for="sessionid" />
</h:panelGroup>

This is a bean:

@Named("ValidatorController")
@ViewScoped
public class FormValidator implements Validator {

    public FormValidator() {
    }

    @Override
    public void validate(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        if (value.equals("test")) {
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
                    "  Session ID is already in use, please choose another.", null));
        }
    }

    public void validatebean(FacesContext context, UIComponent component, Object value) throws ValidatorException {
        if (value.equals("test")) {
            throw new ValidatorException(new FacesMessage(FacesMessage.SEVERITY_ERROR,
                    "  Session ID is already in use, please choose another.", null));
        }
    }

}

In the WELD documentation:

Managed beans with an @SessionScoped or @ConversationScoped scope must be serializable, as the container passivates an HTTP session from time to time.

There may be other reasons, but your CDI bean session should at least implement an interface Serializable:

@Named("ValidatorController")
@SessionScoped
public class FormValidator implements Validator, Serializable {
...
}
