It has been suggested on the Python list that one way to get Java and

a CPython process (running, say, Zope or using ZODB) and a Jython
session, which in turn has intra-process access to Java modules and
libraries.

Although that would probably work, I suspect that using Corba would be
better. There is  pure-Python Corba interface available, called fnorb
(see http://www.fnorb.org) which would avoid any need for
platform-specific extension modules. fnorb was originally written by the
Australia DSTC (Distributed Systems Technology Centre), an
academic-industry co-operative research centre. It used to be available
only under a commercial or research-only license, but now it is fully
open source.

A (very) small proof-of-concept project illustrating the use of Corba to
communicate between a Java app, say some aspect of OpenEMed, and a
Python app, would be great. I would be interested in participating, but
it would need a Corba expert to lead it (hint, hint). We aim
(eventually) to create a PIDS (patient identification service) as part
of our probabilistic record linkage research project, Febrl (see
http://datamining.anu.edu.au/projects/linkage.html), and we are thus
very interested in exploring the use of Corba with Python. I suspect
that other Python-based projects, such as TORCH and GNUmed would also be
interested (although support for a range of interfaces is needed by most
projects these days, including XML-RPC, SOAP and WSDL and of course HL7
- none of these are as good as Corba, but all of them are more widely
used, so they can't be ignored).

It should be quite trivial to connect up a python CORBA client to a PIDS server.
We have sample serves running all the time, if people want to try. Just let me
know so we can try this out sometime. Doing so with security is probably
a somewhat bigger challenge. Remember PIDS handles HL7 data. It would
be possible to so with SOAP, but the standard interface for doing so is not (yet)
defined.
