Hi Julio,
Thanks for your response, however, it does not solve my problem to not print any
HTML (that's what I'm doing). The problem is in the line of code
out = pageContext.getOut();
As soon as you getOut(), even if you close it, you can't do a redirect or you
get the IllegalStateException!! :-( Once you've got the out, it's too late.
And there is, as far as I can tell (hopefully I'm wrong), no way to tell tomcat
NOT to generate a getOut() even if you never write anything to it in your JSP.
This line is *always* generated. Which is unfortunate.
