I have to say that we've been doing the ignoring, turning our backs when Ozzy jumps up ever since we've had him - hasn't done a blind bit of good, he still jumps up! He will get down if asked, mostly, but it doesn't stop him jumping up in the first place - it drives my OH mad! I wish I could think of something to stop him jumping in the first place, but, I've come to the conclusion that it's just a cocker thing!
