I guess my lack of understanding is how you're able to throw 2 exceptions
w/out catching one first?  e.g.

try {
	throw something
	// you'll never get here
} catch (something) {
	// here we are!
} finally {
	// at last!
}

So here's your flow of control:

Some JSP page, throws unhandled --> error page, handling it.

Please revise the above line include how you're throwing 2 exceptions.

Am I on the right track here?  Course project due in 45 minutes, so I'm a
littly fuzzy right now =)
