Hi Zac, 

I have managed to successfully use the subscribe methods having slide server 
as backend ( never tried / needed to with exchange ).


Basically, what I do is subscribe an instance of 
org.apache.webdav.lib.NotificationListener to the server this way 

systemListener.subscribe(method,ROOT,DepthSupport.DEPTH_INFINITY,
SUBSCRIPTION_LIFETIME,NOTIFICATION_DELAY,systemSubscriber,systemCredentials)

where 
1 - systemListener is an instance of  
org.apache.webdav.lib.NotificationListener with a custom notify method
2 - method is a string that represents one of the supported methods by the 
server
3 -  DepthSupport.DEPTH_INFINITY ... check the API ;)
4 - SUBSCRIPTION_LIFETIME is the lifetime (in milliseconds ) to keep the 
subscription alive,
5 - NOTIFICATION_DELAY is the delay is seconds between the notification and 
the action in response of the event
6 - systemSubscriber is an implementation of org.apache.webdav.lib.Subscriber 
with a custom notify method
7 - systemCredentials is an instance of UsernamePasswordCredentials for 
logging into the dav server .

keep in mind that I had to activate the notification framework in slide ... in 
Domain.xml set <notification include-events="true" />




hope it helps.


cheers 

Marco
