Re: Quick question...

There is an sourceforge project called 'destiny' that is an HTTP bridge to
JMS.
You could use that as a starting point to implement that same HTTP API used
by mod-pubsub. There's nothing magic about the server implementation of
mod-pubsub, it's all in the protocol. If mod-pubsub had a multi-server
protocol for a constellation of messaging servers, that would be more work
to 'port', but still doable.

The java client I built is on the old mod-pubsub API, I don't think it's
compatible with the new server implementation.
There are actually two java client libraries in CVS for mod-pubsub. One has
lots of unit tests. Mine doesn't... but still works.

Let me know if you need advice or additional work for a java client or java
server - i'd love to help implement a java server.

I'd also like to implement an RSS format for 'change-lists' (lists of recent
events) that use 'next' and 'prev' links to traverse past and future
history - I think that's the correct approach for a REST based event
notification system.
