Jersey RESTful Web Services 3.x framework is open source, production quality, framework for developing RESTful Web Services in Java that provides support for Jakarta RESTful Web Services 3.0.

Developing RESTful Web services that seamlessly support exposing your data in a variety of representation media types and abstract away the low-level details of the client-server communication is not an easy task without a good toolkit. In order to simplify development of RESTful Web services and their clients in Java, a standard and portable JAX-RS API has been designed.

Jersey framework is more than the JAX-RS Reference Implementation. Jersey provides it’s own API 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.

The major change from Jersey 3.0 and the 2.x line is the use of the new Jakarta namespace (jakarta.ws.rs), which is a breaking change, along with the use of Jakarta EE dependencies such as Servlets (5.0), which also has a change in namespace (jakarta.servlet)
