Treffer: Toward Integration Java Business Integration

F or as long as I can remember, an argumenthas been making the rounds in distributedcomputing circles about how best to define interfaces for distributed elements. Some advocate the use of an interface definition language (IDL), whereas others prefer to use programming lan-guages directly. (There are even those who prefer to avoid explicitly defining interfaces altogether, but I’ll ignore that position for now.) Not surprisingly, the Java community has tra-ditionally sided with the programming language approach — arguing, in part, that IDLs are too far removed from the languages that developers use for implementation, and that the resulting mis-match often makes it difficult to map between the two. In practice, this means that either the IDL forces the developer to use an unnatural program-
