I am wondering how to get ZClass instances from Zope to a Java XML-RPC client. 1. I have (and please forgive the Java-like pseudocode; i'm new to Python) a product with a ZClass call Invoice (meta = "Invoice Main") class Invoice { String invoice_name int invoice_id date invoice_date } 2. I have a Python Script (named 'invoice') that goes: results=[] for object in context.Projects.objectValues('Invoice Main'): results.append(object) return results 3. When i test this script directly in Zope, i get: [<Project instance at 014A00F0>, <Project instance at 01832800>, <Project instance at 015A2D80>] 4. If i call this from my XML-RPC client, i get the following Java/Zope error: Unexpected Zope exception: cannot marshal <extension class Acquisition.ImplicitAcquirerWrapper at 00C25140> objects org.apache.xmlrpc.XmlRpcException: Unexpected Zope exception: cannot marshal <extension class Acquisition.ImplicitAcquirerWrapper at 00C25140> org.apache.xmlrpc.XmlRpcException: Unexpected Zope exception: cannot marshal <extension class Acquisition.Impl icitAcquirerWrapper at 00C25140> objects at org.apache.xmlrpc.XmlRpcClient$Worker.execute(Unknown Source) at org.apache.xmlrpc.XmlRpcClient.execute(Unknown Source) at TreeExpandEventDemo.init(TreeExpandEventDemo.java:49) at sun.applet.AppletPanel.run(Unknown Source) at java.lang.Thread.run(Unknown Source) It seems that it's not getting actual instances, but references to them. I don't know. I am assuming that the results array of objects above should come back as a Java hashtable, per this page: http://xml.apache.org/xmlrpc/types.html Anyone explain what's going on and how i get the ZClass instances (or Python class instances) out of Zope and into my little applet?? Thanks much! mark ------------------------------------------------------------ Sent via Marzie's Toolbox (http://www.marzie.com) ------------------------------------------------------------
