Automating the Ada binding process for Java — How far can we go?

This paper describes an automated approach for generating Ada bindings from Java class files. We start with the set of Java features that require a visible Ada binding, and an Ada compiler's definition of how to interface Ada and Java. We discuss how to obtain the Java definitions from the class file and then translate them into an Ada binding (using the GNAT binding approach). While it is possible to generate a technically complete Ada binding from the information in a Java class file (within the constraints of necessary support from an Ada compiler). However, we show that such a binding has significant limitations from a practical usability perspective.
