Apache Karaf REST Example

Abstract

This example shows how to use JAX-RS to implement a REST service.

This example uses blueprint to deal with the jaxrs-server and Apache CXF as the implementation of the JAXRS specification.

It implements a BookingService with a REST implementation.

The "client" bundle uses the BookingService with a REST client stub.

Artifacts

• karaf-rest-example-api is a common bundle containing the Booking POJO and the BookingService interface.
• karaf-rest-example-whiteboard is a whiteboard bundle providing the BookingServiceRest implementation of the BookingService interface.
• karaf-rest-example-features provides a Karaf features repository used for the deployment.

Build

The build uses Apache Maven. Simply use:

mvn clean install

Feature and Deployment

On a running Karaf instance, register the features repository using:

karaf@root()> feature:repo-add mvn:ru.agentlab/karaf-rest-features/LATEST/xml

Then, you can install the service provider feature:

karaf@root()> feature:install karaf-rest-whiteboard
