What are the best resources to learn and implement REST in Java EE projects?

Although there are various resources, but nothing as helpful as video tutorials. I highly recommend you to watch video series from Java Brains, the guy is great in explaining complex topic easily. https://www.youtube.com/playlist?list=PLqq-6Pq4lTTZh5U8RbdXq0WaYvZBz2rbn For best pattern reference watch this video tutorial https://www.parleys.com/play/1397 For Reference you can refer various book as other have mentioned, here are few which have good cover on REST in Java 1. http://www.amazon.com/RESTful-Java-JAX-RS-Bill-Burke/dp/144936134X/ref=sr_1_1?ie=UTF8&qid=1437807233&sr=8-1&keywords=RESTful+Javahttp://www.amazon.com/RESTful-Java-JAX-RS-Bill-Burke/dp/144936134X/ref=sr_1_1?ie=UTF8&qid=1437807233&sr=8-1&keywords=RESTful+Java 2. http://www.amazon.com/RESTful-Java-Patterns-Best-Practices/dp/1783287969/ref=sr_1_2?ie=UTF8&qid=1437807233&sr=8-2&keywords=RESTful+Java Hope it helps, feel free to query for more!
