JNI provides tools and defines language bindings, allowing you to pass Java objects and types to a native language adapter, which can then convert them to native language types before forwarding them to the target library. Although JNI can generate skeleton code for an adapter, you must implement the adapter yourself. Thus, although the scheme used is highly flexible, you must ...
