You should be aware that some newsreaders strip the subject line, making
your question appear to be nonsense. You are asking if the responses to a
weak jump overcall (2H or 2S) are the same as to an opening (weak) 2H or 2S.
Personally, I describe my WJO's as equivalent to a weak two, same basic
strength and shape if partner has not passed. For me, therefore, it's
reasonable to respond (or "advance") as if to a weak two, including new
suits as forcing and 2NT as an inquiry (features or Ogust.) The cue-bid of
opener's suit requires discussion, but in any case is clearly forcing. I
would assume absent discussion that it is a strong raise, setting the stage
for a penalty double if they bid over our game.
Those who make a WJO on hands of 2-5 hcp or whatever may prefer a different
scheme, but I can't offhand see much reason to play new suits or 2NT as
non-forcing. Some people play virtually every weak bid they can think of ("I
never get good cards!") and unintentionally rely on body language when they
have a strong hand for which they have no bid. Doesn't work very well online
