Hello,
I am using Tomcat 7.0.14. I used to have a servlet implementing CometProcessor
to process asynchronous streams, with timeout set very high
(Integer.MAX_VALUE), and all worked fine. When I close the browser, the servlet
is notified immediately about that (CometEvent.EventType.END) and I am happy to
do the cleanup.
No, I have created an async servlet 3.0, and all works as I expected, except
for notification when the browser is closed. I used request.startAsync(), I
added AsyncListener, and none of the events get fired when the browser is
suddenly closed. Since I set the timeout to a large value (Long.MAX_VALUE),
AsyncListener.onTimeout will never get called.
As far as I understand, onComplete will get called only when I call
AsyncContext.complete(), and I do not know when to call it. I tried to write on
response.getWriter(), expecting to see an exception, but no exception was
thrown after a couple of writes.
How can I handle this situation using servlet api 3.0, when the user closes the
browser or hits the stop button? I need to do the cleanup for that
client.Meanwhile, I reverted the source code to CometProcessor.
Thanks a lot,Paul
