Non-blocking SOAP::Lite access

P Dobranski

2008-05-06, 8:43 am

I have a need for access to a web service via SOAP from within a POE-based
program.
I would like that access to be non-blocking, which leads me to think that
the SOAP::Lite service object needs to
be implemented from within a POE::Wheel::Run.

I've looked through CPAN and didn't really see an out of the box module for
such non-blocking SOAP requests
(I'm the SOAP client, not the server).

Are there any more efficient means to accomplish my goal or is
POE::Wheel::Run the right path to follow?
Thanks for any input you might have.

You could also look at the current POE::Component::Server::XMLRPC
server implementation (that is growing rusty with bitrot at the
moment). It makes use of XMLRPC::Lite (in the same space as
SOAP::Lite) for ideas on how to do this non-blocking style

HI,

If you are looking to implement asynchronous non-blocking outbound web
services take a look at POE::Component::Server::AsyncEndpoint

Each endpoint will run a separate process so it does no affect other
services. Yo cal pull stuff via SOAP on one side and publish it on a
STOMP queue. Then on the other side (or other system) you can subscribe
to the STOMP queue and push the info via another WebService.

Take a look at the POD which is pretty extensive and the slides
available at

http://p2ee.org/docs/PoCo-Server-As...-%20English.odp

The AsyncEndpoint is still a little quirky but it is working in a
production environment. There is still a long way to go but please let
me know if you are interested so I will hurry the next release which
will include a number of small fixes.

Nicholas, Alejandro, thanks for the excellent suggestions.

I think between Poe::Component::Server::XMLRPC and
POE::Component::Server::AsyncEndpoint I should be able to glean enough
details to get something working with SOAP::Lite.

For Webservice work you might be better off using XML::Compile. It seems much
more logical, and takes care of all the SOAP handling.
