I am involved in a similar project: we want to replace the current
inter-application communication techniques (RPC's, batch files etc) by XML
document exchanges. This because XML makes the interfaces more flexible.
We need methods and tools for the programmers who have to adapt old
applications, or build new applications that communicate through XML to
other applications.
The problem is that these programmers are used to RPC's etc. If they have to
use DOM, that would probably mean a lot of education and a lot of changes in
current applications. Also a lot of programs are written in COBOL, which
makes it more difficult to use DOM I think.
The question is: what methods and tools can you offer these programmers?
What is feasible?
DOM? Which implies that the programmer constructs and sends an XML document
instead of calling a remote procedure.
DCE IDL? The programmer uses RPC's (as he does now), which are translated by
underlying middleware to XML documents?
But is this a practical solution?
What about using UML for your data definitions and then create stubs?
Any ideas?
