xmlrcp register classes

[Sergio Rua]

Hello,

I have a structured program with several classes which I would like to
export using a xmlrpc server. I'm doing this

Server = SimpleXMLRPCServer (('127.0.0.1',8080))

Server.register_instance(MyClass1())
Server.register_instance(MyClass2())
Server.register_instance(MyClass3())

What is seems to happen is that only the last class I register it is the
only one being exported. How can I register all the classes? Thanks.
