def extmethod(self, REQUEST): return str(REQUEST)

From the web that prints the string Representation of REQUEST. But, over XMLRPC, this:

s=xmlrpblib.Server("http://server.name/Zope/path/") s.path.extmethod()

Returns the string representation of REQUEST, but *this*

s.path.extmethod('rrr')

return 'rrr'. What's happening? That's the ZPublisher magic:

it tries to match the requirements of the called object with what is provided by the request. In your first example, you did not provide a parameter, but your function requires one. ZPublisher determined the "REQUEST" object as candidate based on the parameters name. In your second example, you did provide a parameter. ZPublisher used this positional parameter to satisfy the first positional parameter of your function. Thus, if your function requires two parameters: say 'text' and 'REQUEST', your second example would behave as your first now does. There is a document on zope.org that describes this ZPublisher magic in more detail. But maybe, you already know enough to fulfill your requirements. Dieter
