Well, you have certainly been busy! I wish I knew more so I could better understand what you have done, but one thing I do know, is that it must have been a heck of a lot of work! Hopefully, you will now be getting some help!

I have been working on a toolbox of java bridge components that I'm calling m2java (i know, not very original). As part of this effort I looked at the "java" files included in the VistAWeb sources, in particular the MDO package. I'm not sure, but I think this code is written in some sort of a Microsoft contamination of Java. Anyhow, with a little effort I was able to rework most of the protocol code to be Java compliant. I haven't had a chance to test it out yet, but I will release it shortly on sourceforge.
Following is a summary of the components I've put together:
rpcbrokerj - a repackaging of the VistAWeb rpc broker client as a standalone pure java component.
mj - m parser written in java. Very primitive, doesn't use a proper grammer and generator such as javacc, but it is simple and can be used for building code analysis graphs.
gnpj - Java port of the GT.M GNP protocol which can be used for accessing GT.M globals from java (over TCP sockets).
sshscraper - XML based screen scraping state machine that uses Mindterm SSH. This includes scripts, based on Mark Street's installation instructions, for installing and configuring OpenVistA. The variabilities are supplied through properties files and can be driven by ANT scripts.
filemanj - java wrappers for fileman meta-data elements.
Any thoughts or feedback would be greatly appreciated.

Labor intensive I'm sure, but you wouldn't to be quite as low level as true reverse engineering.
But then again, if the VA already has some first steps with a web access, doesn't that mean that a java tool already exists?

Except, of course, that the wire protocol used by the RPC Broker isn't documented. If it were, writing a Java implementation without having to resort to reverse engineering the thing would be much easier.

Best place to start will be with the RPC Broker
documentation and
code. That
defines the communications with OpenVist from the
client side I
believe. The
CPRS code will show you how the client now works
and what kind of
messages
you will need to send toward Vista in order to
perform the Clinical
