My codebase relies on an internal TCP layer implementation which does TCP session multiplexing using a non blocking selector pattern (java.nio). This means I can create a single threaded app that can handle any number of TCP sessions.
The application I am working on should ideally be single threaded. I can't find a way to have QuickFIX/J run on the same thread my application is running on. Would there be a way for me to use QuickFIX/J only as a pure FIX protocol translator by passing the data in/out of my TCP layer into QuickFIX/J?
