Jersey is an open source framework developed by Oracle. It is the official reference implementation of JAX-RS API, which is very similar to Apache CFX. On the server side, Jersey provides a servlet implementation that scans through the predefined classes we define to identified the restful resources. In the web.xml file, which is the deployment file for web applications, we can configure either the restful servlet or the jersey servlet.
Jersey provides the implementation of the client library, which is fully compliant with the JAX-RS API. It also provides several tools for security such as authorization or bean validation. Furthermore, it allows us to integrate testing for container deployments. The current version of Jersey is 2.27. You can learn more about Jersey by going to its official website at http://jersey.java.net.
