JSR-311 (JAX-RS) is one of the simplest, most elegant of all the Java EE specifications. It enables you to create RESTful web services from POJOs by sprinkling a handful of annotations on them. As of Java EE 6, JAX-RS resources can now tie into the rest of the Java EE platform through the use of the standard contexts and dependency injection.
facility (JSR-299: CDI).
Seam's RESTEasy module takes this a step further by allowing you to use JAX-RS annotations on your existing Seam components, giving your REST resources access to the Seam container, infusing them with enhanced security, persistence management and other Seam portable extensions. You'll also discover that Seam eliminates the configuration required to add JAX-RS to your application and you'll be enthralled by the module's innovative approach to doing CRUD over REST. Using Seam, CDI and JAX-RS together let's you REST like never before.
