Novice question: Can Web Service call client application?

P: n/a
I'm novice here and I'm sorry for stupid question. We are trying to
understand web services architecture, is it better than TIBCO.Randevouz and
does webservices fit our needs.

I understand, I can make web servce and a client applicaiton. Client will
call the service and will receive some kind of responce.

But can my client applicaiton receive EVENT from web service? Can I
"subscribe" to, let say, "Clock" web service and web service will send time
update to client? Can web service "push" data or I always have to "pull" data?

thank you.

P.S. if somebody could point me to documentation about "why web services
better than..."

Dear Dmitry,

the way we have implemented this is by using a windows service, which is
called by the webserver (over remoting):
a client subscribes to the windows service (over remoting) while a
webservice publishes on that service. The service notifies then alle
subscribed client.
