I\'m trying to validate two password fields with JSF but no good until now, I search for it on google but everything was about JSF 1.2 and pretty confusing, I\'m using JSF

With seam 2 you have the component and you don't need to write code. For JSF2 then you have Seam 3 modules, particulary Faces module and Cross-field Form Validation. An example :

First you have to use the s:validateForm tag:

and the corresponding Validator for the password form above would look like this:

@FacesValidator("PasswordValidator")
public class PasswordValidator implements Validator
{
   @Inject
   @InputField
   private String newPassword;

   @Inject
   @InputField
   private String confirmPassword;

   @Override
   public void validate(final FacesContext context, final UIComponent comp, final Object values) throws ValidatorException
   {
      if (!confirmPassword.equals(newPassword))
      {
         throw new ValidatorException(new FacesMessage("Passwords do not match!"));
      }
   }
}
