This exception is often thrown when you try to send a redirect after writing some text out to the output stream. Is it possible that you are using a JSP that has a lot of logic at the top, some output, and then a conditional <jsp:redirect> tag or something like that? Usually, there's a message along with the IllegalStateException that says something like "cannot redirect after response has been committed" or some such, so this might not actually be the problem. Check it out, though; it could save you a lot of time looking for other problems. -chris
