rest 기반의 웹 서비스를 쉽게 만들기 위한 framework 도입을 위해서 대충 알아보니, 아래와 같은 framework들이 존재하네요.. 흠, 몰 써야 할까요?? 모르겠넹.. ^^;;

* Restlet is a lightweight REST framework for Java

* Jersey is the open source (under dual CDDL+GPL license), production quality, JAX-RS  (JSR 311) Reference Implementation for building RESTful Web services. But, it is also more than the Reference Implementation. Jersey provides an API  so that developers may extend Jersey to suite their needs.

* JAX-RS: CXF has an implementation of JAX-RS 1.0 (JSR-311): Java API for RESTful Web Services. This provides a more standard way to build RESTful services in JAVA.

*  JBoss RESTEasy is a JBoss project that provides various frameworks to help you build RESTful Web Services and RESTful Java applications. It strives to be standards based wherever possible, but to also innovate when appropriate.
