Re: [Zope] Want to access ZClass Instance from external program
This works like a charm. Thanks much for the help.

Sorry Jon, i've lead you down a slippery slope...
unlike ttw dtml-methods and the rest of zope which relies on the
security context soley, for a filesys python method to be exposed
through the web via xml-rpc it must have a doc string as well as have
proper credentials.
looking through propertysheets there is no 'proper' way to do this...
but i lead you down the path, so here is a way back out...
there are a couple of options.
the easiest is to have dtml_method for this zclass that functions as a
helper method,
like
dtml method -- external_helper
dtml-var "propertysheets.propertyMap()"
and in the client
x = root.subfolder.zclass.external_helper()
meta_info=eval(x)
print meta_info
({'id': 'vvv', 'type': 'int', 'meta': {}, 'mode': 'w'}, {'id': 'aaa',
'type': 'lines', 'meta': {}, 'mode': 'w'}, {'id': '', 'type':
'tokens', 'meta': {}, 'mode': 'w'}, {'id': '122', 'type': 'date',
'meta': {}, 'mode': 'w'}, {'id': 'ff', 'type': 'float', 'meta': {},
'mode': 'w'}, {'id': '', 'type': 'text', 'meta': {}, 'mode': 'w'})
or if external_helper returned propertyItems()
[('vvv', 1), ('aaa', ['']), ('', ['ss', 'aa1113', '3', '4']),
('122', DateTime('1900/01/01')), ('ff', 455.0), ('', '')]
if you're working with DateTime values in your propertysheets this will
be trickier as you'll need to either retrieve the property you want
independently or import Zope's DateTime module. also remember to set the
security on the helper method so its not helping somebody hack your
site.

hmmm...
try and take it a step back and query the propertysheet container for
names of propertysheets it contains. you'll need to check out the ZQR
for the syntax, i think its propertyIds().
you might also want to check that your authenticating with a user
that has the proper security roles to query this info.
if you're still having problems tell me and i'll play with it once i get
back from work.
