The purpose of this project is to compare/contrast java and clojure implementations of naive matching (stock) price engine.

Expected hyposis is that:

1. java implementation should be a bit faster (2-9 times)
2. clojure implementation should be much shorter and modular

• bin - fat jars for the implementations
• jcmec - clojure implementation
  • builds with leiningen
  • uses ring (jetty 6x), moustache
• jcmegen - clojure client that generates input, calls into web service/s, verifies and prints results
• jcmej - java implementation
  • builds with maven
  • uses CXF (jetty 7x)
• build.sh - bash script that builds the implementations
• buid_run.sh - bash script wrapper that invokes build.sh and then run.sh
• config.clj - input configuration in clojure reader compatible format
• README.md - this file
• run.bat - Windows version of run.sh
• run.sh - invokes main of jcmegen against pre-build jars in bin

1. REST JSON interface
   • POST /match
     • json: orderId (B|S plus sequence number), price
   • GET /max/B|S
   • GET /results
   • GET /reset
2. Support concurrent requests for match and get max buy and sell price.
3. Return unmatched items.
4. Reset internal state so matching session can be repeated.

./run.sh || run.bat

Make sure maven and leiningen are installed and on the PATH ./build_run.sh

1. Port the rest of bash scripts to Windows bat
2. Implement scala version
3. Implement haskell version
4. Collect run statistics: jcmegen will call into public web app which will store and report on run statistics.
