jsp pages not exeuting

I receive the following error message when I try to execute jsp pages on my coldfusion server.
Everything else about the server works fine, I can execute CFM pages ok without a problem but not jsp pages.

Does anyone have any ideas as to what might be wrong?
I have tested this on CF8 adn CF801
