Isn't the error message pretty clear? The code throws an IOException, and the method neither catches it, nor declares that it throws it. That's a no-no.

By the way, keeping Java code in JSPs is really bad design. 10 years ago that might have been acceptable, but not today. That's what servlets and backing beans are for.

JSPs like this make me want to cry.
