I would do the same thing as Trixie when Java would start jumping up - cross my arms and turn my back and ignore her until she calmed down. Once she composed herself she would get lots of (calm) loving and maybe even a treat along with praise. Like all other puppy training, this takes a while, but it is so worth it. Now that she's 72 lbs of solid muscle, I'm glad that Java doesn't jump up as she could easily knock someone over.
