Subject RE: JSPwriterImpl generates IO exception while processing <jsp:include> that gets forwarded.
Date Sun, 26 Jul 2009 01:46:02 GMT

dont understand why you want to forward before jsp:include has been processed? 

could you explain a bit about webapp architecture or workflow you wish to implement?
