Hmm. Not a good clean separation there.

Why do you need so much Javascript?

The Aptana plugin for Eclipse
www.aptana.org
provides more advance Javascript editing.

It seems wrong to put a lot of JS into a JSP. Or any, really.

I've seen it done in some projects and that consistently caused unholy messes.

But you might try using static pages with the same Javascript and debug the JS that way.
Freeze one possible output that the JSP might generate and try to use its Javascript.
