Hi John,

I read in a CC mail from Jorgen, that you are searching for an Interop 
Endpoint for your plumbwork orange project.

The Apache Hermes[1] project will be an implementation of WS-Notification 
and WS-Eventing for Java. It will use one abstract API for both specs.

We are in early development phase, but I have set up an Interop Endpoint 
for you[0].

This Endpoint is a message Broker, it means it implements both Subscriber 
and Event Source. 

For example you can do the following:

1) Make a Subscribe Request to the EventSource[2]. please don't forget 
<NotifyTO> in <Delivery>

2) make a notification that matches to the above given XPath Filter to the 
notificationPort[3]

3) now all the matching subscriptions will get a notification on the 
NotifyTO EPR.

4) Make an Unsubscribe Request to the SubscriptionManager[4]

5) now you can do 2) again and 3) wont happen :-)

This implementation makes use of YFilter[5] for efficient and paralell 
XPath filtering, so don't hesitate to make millions of Subscriptions :-)

Please contact me, for any questions, problems and bugs, cause 2005 will 
be the year of WS interop[6] and i really like to see interop between 
plumbworkOrange(.Net) and Apache Hermes(Java).
