thanks remy for the information that helps. What if I decide to buffer
the response myself in a response wrapper? Does catalina try to call
clearBuffer, reset, resetBuffer, flush or flushBuffer in the event a
request is passed to my errorpage? Also, does the status code change
and the exception set in the request object with
request.setAttribute("Throwable") if html has already been sent to the
browser?
If you buffer everything, then Jasper will do a forward instead of an include.
I think you should, since in the end it should be the same (something will need a buffer to hold your bytes, right ?).In cases where the exception occurs before any content is sent to the browser, it all works fine. I need to ensure exceptions display my custom errorpage, but I'd rather not set the page buffer to an arbitrarily large 64K or 100K.
If I were you, I'd try to set a big servlet buffer size rather than a big JSP page buffer size (that doesn't run into the issues a servlet like Jasper has when trying to recycle things while being thread safe, so it would be more efficient; plus it will compute the content-length now).
