Teaching a cat not to jump on the counter.?

How can I teach my bengal to not jump on the computer desk? For a long time I just was stern with her saying "NO!" and putting her on the floor but that hasn't seemed to stop her. The other day I decided to try the water spraying technique but that resulted in her biting my hand, which in turn resulted in me having to go to the hospital. Now I'm a little nervous to be around her... but I know that letting her continue the behavior won't teach her at all. If anyone has any suggestions I would truly appreciate it. =)
