Novice question: Can Web Service call client application?


Novice question: Can Web Service call client application? Dmitry Sazonov

dotnet web services:
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

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.
