Chapter 11. The REST Interface

Red Hat JBoss Data Grid provides a REST interface. The primary benefit of the REST API is that it allows for loose coupling between the client and server. The need for specific versions of client libraries and bindings is also eliminated. The REST API introduces an overhead, and requires a REST client or custom code to understand and create REST calls.
To interact with JBoss Data Grid's REST API only requires a HTTP client library. For Java, the Apache HTTP Commons Client is recommended. Alternatively, the java.net API can be used.
