Jersey is a REST framework that provides JAX-RS Reference Implementation and more. Jersey provides its own APIs that extend the JAX-RS toolkit with additional features and utilities to further simplify RESTful service and client development. Jersey also exposes numerous extension SPIs so that developers may extend Jersey to best suit their needs.
Goals of Jersey project can be summarized in the following points:
Jersey is licensed under a dual license - EPL 2.0 and GPL 2.0 with Class-path Exception. That means you can choose which one of the two suits your needs better and use it under those terms.
We use contribution policy, which means we can only accept contributions under the terms of ECA.
