[Zope] Product creation difficulty

[Pete Taylor]

*grin*
true enough.

at its simplest level, I've been trying to just import xmlrpclib and use it
normally in scripts.  I used my __init__.py to allow_module('xmlrpclib'),
which has stopped it from throwing security errors.  however, when I
actually run a test script, I get the following:

Error Type: Fault
Error Value: <Fault 1: 'exceptions.Exception:method
"echo.__roles__.__contains__" is not supported'>

error_log has this traceback:
Traceback (innermost last):
  Module ZPublisher.Publish, line 101, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module Shared.DC.Scripts.Bindings, line 306, in __call__
  Module Shared.DC.Scripts.Bindings, line 343, in _bindAndExec
  Module Products.PythonScripts.PythonScript, line 323, in _exec
  Module None, line 5, in testXRPC
   - <PythonScript at /pro4/testXRPC>
   - Line 5
  Module xmlrpclib, line 1029, in __call__
  Module xmlrpclib, line 1316, in __request
  Module xmlrpclib, line 1080, in request
  Module xmlrpclib, line 1219, in _parse_response
  Module xmlrpclib, line 742, in close
Fault: <Fault 1: 'exceptions.Exception:method "echo.__roles__.__contains__"
is not supported'>

I can watch the "POST /RPC2" messages increment on my xml-rpc server, so I
know the message is getting through.  but the xmlrpc server isn't built with
Zope in mind, so "__roles__.__contains__" makes it cough a Fault back at me.


the code I have in the python script is as simple as:

<code>
import xmlrpclib
server = xmlrpclib.ServerProxy("http://localhost:9999")
server.echo('this is a test')
</code>

echo just sends the recieved string back.  it works from command line, but
that's not surprising...  I could be wrong about where or how it's failing,
but the traceback looks like the message is getting there, and returning
with the "echo" method having been wrapped in a zope security check, thus
faulting at the server...

Thanks for any help...  this list is the best I've participated in.  You
guys are awesome.

You'd have to give us more information if you want help with that, it 
sounds like something bizarre is happening that shouldn't ;-)

cheers,

Chris
