Re: [Quickfix-users] need for SwingUtilities in trading system application?

Well, the only reason that invokeLater is being called is due to the 
requirement that Swing components need to be updated in the dispatch 
thread.  If you are not using Swing, this requirement goes away 
completely and there isn't really a need to make an asynchronous call 
at all.  Just do whatever you want to do in the fromApp method.  Just 
make sure to synchronize your objects where necessary.  If you do not 
want to deal with threads at all then you should use the poll() method 
in place of start().
