Hi All
Is there any way or example how to configure plonePAS to
consume a web
service (in my case JAX-WS via SOAP ) in order to get user
details?
This won't be a configuration issue, it will be a coding issue. You
don't mention specifically what "consume a web service" means,
but you
might be able to put together a Scriptable Multiplugin or write your
own filesystem-based plugin to do the job.
However, there is one big caveat. Making HTTP calls (or almost any
other network request) out of Zope code during the execution of a
web
request is risky. The executing thread will wait until the external
request has been answered, and if for whatever reason no answer is
received it will hang forever. There are four threads available in a
normal Zope configuration, the fourth time this happens your website
will be unavailable and Zope must be restarted. A lot of care
needs to
be taken to ensure there are sensible timeouts on these external
calls
to prevent hangs.
You can get around it, though, if you use something like Zasync. A
bit
heavy-handed, but it's there for ya. :^)
You can't authenticate asynchronously -- the original request is
stalled
untill the out-of-process call returns, and there is no way to release
the thread / connection pool it is using.
Well, fine. Bring you "reality" into it. ;^)
