Asynchronous Transfer of Control in SOA (Web Service)

Hi,

I was reading about asynchronous transfer of control in Real Time Java
Specification.

I am wondering if there is any way we can do similar thing with Web Services
in Service Oriented Architecture.

Please let me know your opinion.

Since I don't know what "asynchronous transfer of control" is, I can't tell
why you would want to use it in an SOA. Perhaps you could tell us why you
want to use it in an SOA.

Hi John,

I was considering following scenario

I have some time consuming math function that tries to converge the
calculation as web service at server. There is client web service that wants
to use this calculation function but wants the approx result calculated after
10sec.

So, what I want is the client service should start timer for 10 sec and call
the server service to perform calculation. But after 10 sec, it should
interrupt the calculation at the server side and get back the converged
result to the client.

I have not seen any such example with .Net SOA Framework.

Could you please let me know if this kind of scenario could be possible ?

Let me know if you need any further information.

Regards,
Kaushal Mehta.

That doesn't sound like the kind of thing that web services were created
for, at all. They're not meant for any sort of interactive scenario,
instead, they are geared toward a request/response scenario.

May I ask you for some references to where this concept comes from? Since I
can't imagine why this is a good idea, I should probably defer to those with
a better imagination than mine.

I found an article that is about the sort of thing you may be talking about.
Can you confirm that this is what you had in mind?
