While browsing the project home of VI Java API, I found a link to a great tool contributed by pitchcat. It is a standalone Java application that shows managed objects and data objects in a tree hierarchy, and all the methods attached to a managed object.
I highly recommend it to all the VI Java API developers. Why? Although you can get similar information from MOB, vijava browser gives you an overview of all the managed objects and clear paths to any managed objects or data objects.
