Wax might help, but either way, you're gonna have to deal with Her Highness....

To do this, you either have to find a way of making places the cat likes to leap upon more unattractive or shoo her off consistently....To prevent The Bean from jumping on the living room coffee table, we place magazines, books, etc. to giver her little room to hunker down. Short of that, you have to catch her in the act and respond with a short, sharp "Git!" and a clap of the hands. A water pistol might help. At the same time, make sure that there are some places that are "safe", like a certain chair or whatever you think you wouldn't mind it so much. She'll soon make the connection, but it takes diligence and perseverance to get the payoff...

You can also take a zomboni to it and make it so slick she slides right off, but this might be excessive...I donno....
