Does the dog also jump up at the door/window when you're inside and she's outside? We stopped a previous dog jumping up by taking one step back each time he jumped up at the door and would tell him to sit. For each time he sat, we'd take a step forward. If he jumped again, we'd go back. After a few days, he got it - we wouldn't go near him if he was jumping up.

The other thing is getting down to the dog's level. As soon as she does the right thing, drop down so you're at the height of the dog, giving her no reason to jump. We did this with a German shepherd too and it worked (mostly!) quite well.
