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 The XML-RPC tries to serialize (Java terminology; its called "marshal" in Python/Corba) the instances and it unable to do it.
Probably, you must convert your instances into something more elementary to help the marshaling process. Dieter
