Re: [Quickfixj-users] [ASK] Monitoring Connection in QuickFIX app

[Colin D. <co...@ma...>]

I believe Bayu is saying that they use a timer to periodically check the 
state of session connections. For my part, I don't see anything wrong 
with this approach per se, though, it would be preferable, as you say, 
to use a SessionStateListener.
