[Quickfix-developers] FIX Session Dropped

[Nick F. <nfo...@gm...>]

A simpler way of doing this would be for the Fix application to hand each
message on to a queue, which is then fetched from by a worker thread which
does the work. That way you only need one extra thread. Be aware this will
add a bit of latency to your application, it isn't a no brainer.

If you are using java 5 there are some nice classes in
java.util.concurrentto help you manage the concurrency issues. Try
looking at
LinkedBlockingQueue or ConcurrentLinkedQueue depending on your design.
