Hi I'd like to try it. However I am not accustomed to building tomcat.
Do you have this compiled somewhere? Best regards, Steffen -----Ursprüngliche Nachricht----- Von: Filip Hanik - Dev Lists [mailto:devli...@hanik.com] Gesendet: Dienstag, 19.

Where you would do CometEvent.interestOps(CometEvent.CometOperation.OP_WRITE); and you will receive a CometEvent.EventType.WRITE When I tried to write sample applications against this, it turned out to be very complex programming. You can check out that branch and build it and see if its something we should still pursue Filip On 01/18/2010 09:06 AM, Steffen Heil wrote: > Hi > > I am using comet connections for some time now in a server push manner: > Whenever the server needs to inform the client about some event, it sends a > packet to the client and waits for a reply in the same connection. > As soon, as a READ event is triggered, that reply is read and the next > message can be sent. > > Now, this requires a round-trip-time between the client and the server and > is inappropriate for larger amounts of data especially on high latency > connections. > > I am seeking for a way to determine (from a comet servlets point of view) if > a connection is writeable - this is, if output buffers are empty and I can > send additional data. > > Note, that sending a huge amount of data at once is not an option, I need to > send distinct parts... > > > So here are my questions: > > - How can I detect if a connection is writeable? > - That is, how can I detect if the output buffers are empty? > - Is there a way to use comet connection for something like a selector? > > Regards, > Steffen > > --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
