Don't know if that will help with the IllegalStateException (you can
get them with RequestDispatcher forward's as well as redirect's). I
believe those occur when you've done something with the response that
you shouldn't do (because it will be done wherever you
redirect/forward to) -- things like open the response output
stream/writer, set certain headers or content type or such -- check
the spec for details. Also not sure what would've changed about this
from servlet spec 2.2 (which Tomcat 3.X implements) to 2.3 (which 4.X
implements), but there are probably some things that did.
