IllegalStateException thrown when you commit the response (<%= out.flush() %> before using forward, include or redirect,e.g. <jsp:include page="">.

[Bear Bibeault]

kalyana, JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.

Please read this for more information.

thanks,

Vince, I'm pretty sure you are allowed to do an include after committing the response, its the forwards and redirects (as well as the creation of a new session) that get you. Just make sure the included page/servlet doesn't do any of these.
