RE: Antw: Asynchronous interface

[Nirmal Mukhi <nm...@us.ibm.com>]

Hello Paul,

WSIF also has an asynchronous invocation model with correlation. You can 
find more details about the async model from 
http://www.mail-archive.com/axis-user@xml.apache.org/msg07607.html, and 
more information on WSIF itself at http://ws.apache.org/wsif

Thanks,
Nirmal.

Yes. I can see how that would work. I'm not convinced that it's a
satisfactory solution in my case for scalability reasons: It requires a
thread for each outstanding request/response pair. I guess you could use
an internal thread pool to manage that but my hope is that if an
asynchronous interface were supported directly by Axis, it would use a
queueing mechanism and leave the issue of threading up to the ultimate
producer/consumer themselves.

There's a difference between an asynchronous API and an asynchronous
transport. You should be able to make asynchronous calls over HTTP, too.

For a description of what I man, see the WASP documentation on
asynchronous
API:
