    Dependency Injection in JSF Validator

    Jboss fan99 Newbie

      Does dependency injection suppose to work with JSF validators? These validators are container managed classes and hence container should be able to inject. my small program:


      directory variable is always null..




      public class EmailValidator implements Validator



          private IDirectory directory;


          private static final String emailRegexPattern = "^[A-Z0-9._%+-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}$";



          public void validate(FacesContext arg0, UIComponent arg1, Object arg2)

                  throws ValidatorException


              String rawEmail = (String)arg2;

              Pattern p = Pattern.compile(emailRegexPattern, Pattern.CASE_INSENSITIVE);

              Matcher m = p.matcher(rawEmail);

              boolean validEmail = m.matches();


              if (!validEmail)


                  FacesMessage msg = new FacesMessage("Invalid Email Address");

                  throw new ValidatorException(msg);



              //now check if email already exists

              boolean emailExists = directory.doesEmailExist(rawEmail);

              if (emailExists)


                  FacesMessage msg = new FacesMessage("Email Address already registered");

                  throw new ValidatorException(msg);
