On the Java side of things you need to convert the JSON array to a Java POJO bean first to be able to (easily) do something with it. There are multiple APIs to do this; Google GSON and Jackson are two possibilities.

Jackson is used internally by Jersey, the reference implementation of the JAX-RS API; it works very well in my experience.
