Message queueing

[Noah Spurrier]

Message queueing
You could also roll your own using Sendmail or qmail or some other mail
server.
That at least gets you a the transport layer. You would then have to add an
interface
for Python or XML-RPC -- and feed mail server error logs back into your
system.
It's easier than it sounds. We did something like this at BlueLight
(K-Mart) -- of course,
maybe that is a bad example ;-) But it worked; it was easy to use and fix;
and easy
to figure out how it was working -- unlike a horrible Java wrapped MQ-Series
thing
they also made us use.

Your XML-RPC to Jython/JMS bridge thing sounds elegant compared to my idea.
Unless you find a better Message Queue then I think that's your best bet.
An XML-RPC interface to JMS almost sounds like a product.

It's sad, but the importance of message queues does not seemed to have been
picked up by the open source community. As far as I can tell there are no
open source message queues... I don't have a job, maybe someone wants to
help
me write one :-)

Yours,
Noah

Hi all,
I am new to this group and could not find an answer after a Google search,
so please bear with me if this question was already asked.
I need to build a distributed app and I am wondering which message queue to
use and if anyone has any experience with interfacing to them in general.
I have played around a bit with Microsoft's using pythonwin to connect to
the COM objects and although this works,  I want to be platform independent
if at all possible.  I am looking into using JMS (Java Message Queue) using
Jython and this seems to be a viable alternative.  I do not want to be
restricted only to Jython as my preference lies with using Python (CPython).
How am I going to get CPython to talk to something written in Java?
So far I have created an XML-RPC "bridge" so that my CPython code can talk
to my Jython based JMS connector.  This entails creating an XML-RPC server
on both sides (for calls and call-backs) but this feels a bit kludgey.
Any suggestions?
Thanks
Etienne
