You are doing something like res.getOutputStream().write(data); twice within the same request. This could be for several reasons and it general occurs when you include a page in your response and then try to use the above - you can do a response.isCommited() to check the state of the response.
-----Original Message----- From: Justin Rowles [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 19, 2001 10:03 AM To: 'Tomcat Users List' Subject: Illegal State Exception At intervals I get this error (or very similar). I have previously got rid of it by removing what I last did! Last time, it appeared to be caused by calling the first() method on a ResultSet. This time I have made several changes and have no idea what the cause is. How can I pursue it through my code from the information I have below?
