We recommend that where possible Java developers should use the Java EngineClient API instead of the more basic low-level management SDK. Also consider using the higher-level EventService API for clients that primarily involve sending and receiving events.

The full reference to the Java EngineClient API is its Javadoc documentation, which you can peruse at doc\javadoc\index.html. This topic introduces the different elements included in the API, and walks through an example.
