Hi,
Just to make my requirement clear..
The event notification is sent to a small group of clients, say 3 or 4..
The number is usually small who register for a specific event..

But what if there are M registered clients, the server need to establish M
HTTP/TCP connections to callback
We certainly can use a Gnutella approach to multi-cast an event.

You're asking for events support, and I don't think Axis has it
because SOAP doesn't (I could be wrong). But have a look at GENA
(general event notification architecture)
http://www.upnp.org/download/draft-cohen-gena-client-01.txt
It is http-based, and this is what UPnP use (they also use SOAP
A SOAP client registers with a SOAP server: send me a message when event
XYZ occurs
The client should register: send me a message AT THIS LOCATION when the
event XYZ occurs
When XYZ occurs, how should the server callback? Is there anything
provided as part of the Axis framework?
