The data returned by searchResults() can not be marshalled since they contain non-basic data structures like IOBTreeItems that can not be transported using XMLRPC. I suggest to wrap the searchResults into a PythonScript or an external method and convert the result to basic datatypes likes lists, dictionaries .... -aj ----- Original Message ----- From: "Sylvain Thénault" <Sylvain.Thenault@logilab.fr> To: "Zope Mailing list" <zope@zope.org> Sent: Tuesday, August 13, 2002 10:04 Subject: [Zope] using a ZCatalog via xmlrpc

hello,

is there some way to use a ZCatalog via xmlrpc ? The following example raises an exception :

import xmlrpclib import xmlrpc transport = xmlrpc.BasicAuthTransport(username='user',password='pass') url = 'http://intranet.logilab.fr:9673/RevuePresse/' server = xmlrpclib.Server(url, transport, encoding='iso-8859-1') server.Catalog.searchResults() Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/lib/python2.2/xmlrpclib.py", line 821, in __call__ return self.__send(self.__name, args) File "/usr/lib/python2.2/xmlrpclib.py", line 975, in __request verbose=self.__verbose File "xmlrpc.py", line 51, in request return self.parse_response(result) File "/usr/lib/python2.2/xmlrpclib.py", line 896, in parse_response return u.close() File "/usr/lib/python2.2/xmlrpclib.py", line 571, in close raise apply(Fault, (), self._stack[0]) xmlrpclib.Fault: <Fault -1: "Unexpected Zope exception: cannot marshal <type 'IOBTreeItems'> objects">

any ideas ? sample of working code ? TIA
