Don't think JSP is failing. It's quite a simple JSP and has been looked at exhaustively!
Yes, I am setting session attributes in Create servlet, for use by create.jsp. I am only using the session object and the request throughout my application. The only time I ever knew I was using the response object was when I used response.sendRedirect(), but I don't use this anymore. I use the RequestDispatcher. There are no <jsp:include> or <jsp:forward> tags being used anywhere, and my servlets do not contribute anything to the response (apart from forwarding it around). Mark - your words of wisdom interest me. I thought that... when I invoke requestDispatcher.forward(), then control never returns (to the line following this invocation). So how do I go about "returning" to the Home servlet from the "Create" servlet. Surely I need to "forward", because the session has changed? I have a lot to learn here I think, but I feel I'm getting closer to the holy grail - getting rid of this exception! -----Original Message----- From: Attila Szegedi [mailto:[EMAIL PROTECTED]] Sent: 08 March 2002 13:56 To: Tomcat Users List Subject: Re: How can I resolve this "IllegalStateException: Response has a lrea dy been committed" problem? I guess you JSP is failing with an uncaught exception. At that point, Tomcat would try to send a "500 Internal Server Error" response code, but it can't since a "200 OK" status code has already been sent (that is, the output committed) to the client. -- Attila Szegedi home: http://www.szegedi.org ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: 2002. március 8. 14:45 Subject: RE: How can I resolve this "IllegalStateException: Response has a lrea dy been committed" problem? > The exception seems to be occurring because the Home servlet forwards more > than once (to different locations) - first to home.jsp, then later to the > Create servlet. > It is definitely the fact that it is forwarding to more than one place, that > is causing the problem.
