[Quickfixj-users] Multi-threading/blocking question

[Tommy H. <th...@bo...>]

I am using threaded initiators and acceptors along with the message  
cracker...

When processing inside an onMessage(...) method, and presumably  
indirectly the fromApp(...) method, am I blocking incoming messages  
or is there a separate thread "queueing" the incoming messages for  
either the fromApp(...) or onMessage(...)?

Is it okay to send outgoing messages inside an onMessage(...)  
callback or should this be done in a separate thread?

Does anybody recommend best practices for this callback processing?
