Folks,

Any one got a better way?

RE: WS-Callback support in Axis?






Hi John, 
 
Ok, here?s the skinny. I have a tradition C/S relationship. The clients 
communicate with the server though normal ole WS calls. However and here?s 
the twist, I need to be able to have the server ?callback? the clients to 
cause them to perform actions based on some server state. 
 
I saw WS-Callback and thought I was good, in that I could create a WS call 
like ?ListenforCmd? and then just have the client pend on the async 
callback. It?s still a polling model, but the clients only need to post a 
new ?ListenForCmd? after receiving an action to perform. 
 
Without this, I?ll have to have the clients constantly calling back to the 
server to find out if the server wants them to do anything, a VERY intense 
polling model.
 
I really need an event driven model or traditional callback model to 
facilitate client control, and un-fortunately for me WS-Callback was a 
pretty good fit. 
 
Does Axis have any paradigms that can help me reach my goal?
 
Thanks,
John

Phew - just ask me the easy ones ;-) 

Do you mean what other clients to use or what sync patterns are there you 
can use?

Thanks John, 
  
What?s the suggested alternative given the current implementation in 
axis-c?

Sorry, Axis C++ does not support async callsbacks.

Try ws-polling  http://www.w3.org/Submission/ws-polling/
Axis might have support for it soon  :-)
