Learn how to create a REST service with JAX-RS, JSON-B, and Open Liberty.
You will learn how to build and test a simple REST service with JAX-RS and JSON-B, which will expose the JVM’s system properties. The REST service will respond to GET requests made to the http://localhost:9080/LibertyProject/System/properties URL.
The service responds to a GET request with a JSON representation of the system properties, where each property is a field in a JSON object like this:

}The design of an HTTP API is essential when creating a web application. The REST API has become the go-to architectural style for building an HTTP API. The JAX-RS API offers functionality for creating, reading, updating, and deleting exposed resources. The JAX-RS API supports the creation of RESTful web services that come with desirable properties, such as performance, scalability, and modifiability.
