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

This is the code that I added into faces-config.xml
<validator>
<validator-id>ValidatorController</validator-id>
<validator-class>com.DX_57.HM_57.FormValidator</validator-class>
</validator>
This is the code of the Validator that I tried to test:
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 correct scope. What scope I have to use?
Best Wishes

From the WELD documentation:
Managed beans with scope @SessionScoped or @ConversationScoped must be serializable, since the container passivates the HTTP session from time to time.
There might be other reasons, but your CDI session scoped bean should at least implement the Serializable interface:
@Named("ValidatorController")
@SessionScoped
public class FormValidator implements Validator, Serializable {
