If you are running in the process, it is just JNI -- you can look online for good references on JNI. Note that this is not expressed as "messages," but just a standard API for invoking methods in the Java runtime.
If you are going across processes, often we do this using the Binder IPC system, but you can use any standard Linux mechanism if that is more appropriate. You could, for example, define an interface in aidl that is implemented by Java, and write the native side of the IPC for native calls. Unfortunately aidl currently can't spit out a native version of the interfaces, so this can be a little awkward.
