Ahhh... I see you are using the DOMConfigurator by having an xml file to specify the plugin... I don't think I can tell DOMConfigurator to use my PluginClassloader class as yet. Could we try creating the Receiver the manual way within the GUI, and see if that works? I know that's a pain, but I think at the moment that's the only place I can get it to use the custom class loader.
You can go ahead and send me your jar (not to this list though).
