This is the demo app for the techniques described in these two blog posts on a Java web stack with Jetty, Guice, Jersey, and Jackson. While the code does still work, I encourage you to check out the following production ready versions rather than this demo-grade app.

• jersey-metrics-filter, automatic metrics for all Jersey resource methods
• jersey-new-relic, Jersey integration into New Relic monitoring
• jetty-http-server-wrapper, a simple wrapper around the Jetty http server
• jersey-cors-filter to apply CORS headers to Jersey HTTP responses
• url-builder to safely build URLs

There's a demo app that shows how to use the above libraries.
