Don't use scriptlets in your JSP. Move this out into a Bean. If you still have a problem, post the Bean, and the JSP tags you use to access it, and we'll continue.

No, your actual probelm is that connection is probably not defined. But that is beside the point. Scriptlets have no place in JSP's anymore. Youre still allowed to use them (mainly for backwards compatability), but you shouldn't be using them. It makes maintenance of the application a living hell.

says it all, the file isn't there.
Place the correct file in the correct place and try again.
