Hi,<br>
<br>
Someone has written a large Java library (QuickFIX/J) which speaks a<br>
gnarled, ugly protocol (FIX). There don't appear to be any FIX<br>
protocol libraries in Hackage. I need my Haskell program to talk to a<br>
3rd-party system that only speaks FIX.<br>
<br>
Should I:<br>
<br>
a) Reimplement the protocol directly Haskell? (This appears to be non-trivial)<br>
<br>
b) Wrap the Java library with some code to use a lightweight message<br>
queue (zeromq) to send messages to my Haskell program? (This would<br>
require essentially re-implementing an abstracted subset of the the<br>
protocol into 0MQ messages)<br>
<br>
c) Find a way for Haskell to interact directly with Java? (the various<br>
JNI bridges seem very unmaintained...)<br>
<br>
To me, (b) seems like the best approach, but I'd like to hear what the<br>
cafe thinks..<br>
<br>
Cheers,<br>
- Dan<br>
