Web services and events
-
Hi all, I am trying to convert an existing DCOM component into a web service. I personally find DCOM is great but is of poor interest in a firewall-dominated world. My good old objects have EVENTS, and I exploited them in order to prevent clients from polling the remote application status. Is there anything similar in web service? Did anyone meet the problem? Any help will be appreciated. Thanks a lot in advance. Best regards, Andrea :)

Hi Andrea, I was wondering about same thing (What if my objects support events?) when going thro web service Why's and How's :) What I found is "Web Service Notification Design Pattern" that sounds something on same track as Events. Check the following search I did on Google - web service notification[^] I haven't done any implementation for it because I was just curios to know why and where one should use Web services and not DCOM. I hope the above link will help you to some extent. Please let me know if you find anything substantial on this Topic. Thanks ------------------------- Have a great day ahead!
