Hi Stephane. It is possible to use a spread client in zope. That said, I am not sure whether you are attempting to integrate the new pb (unstable) or currently stable pb. Either way, I cannot provide code for you but say that this is not trivial. It also requires conforming zope storages to interact with. Your methods need to interact with the zope's storages if you want zope to do its thing properly.

This adds significantly to the complexity since the storage internals of zope take some time to learn and significant time to understand well enough to modify and construct storages. Once you have tested a suitable client server, you will also need to modify zope's startup to include your client service as part of zope's multiservice.


My advice to you is that you may be better off with a web service since this can be configured easily in zope since you are not involving the storage layer directly. It is just part of you app.

Regards,
David

Hi again,
 in order to call my twisted process I need to run the spread client within 
Zope,
 is this possible (maybe through a utility). I'm not sure this would integrate 
well
 with Zope mainly because of the twisted logic (deferred, ...), but I might be 
wrong
 (this wouldn't be the first time ;-)). Has someone had any experience with 
that ?
Thanks, Stéphane

Objet : [Zope3-Users] Using twisted spread client within zope

Hi,
 for my application I have to communicate with external web services,
 these communications have to be scheduled. That is why I use twisted processes
 to communicate with external servers and zope for the GUI side.
 I need to communicate from zope to the twisted processes, has anyone
 done that, especially with spread, or do I need to go through http ?
Thanks, Stéphane
