Hello Simon, thank you for finding this out. There's a snag, however, in that serializing/deserializing a ServiceReference somehow prevents authentication from working. Example: On my reference I have put requires="sca:authentication" and have added a definitions.xml for the policy set just as shown in "Tuscany SCA in Action" (definitions.xml attached). Simply calling the injected reference in my SCA component works fine. Calling a copy of the reference derived by calling serializeServiceReferenceXML() followed by deserializeServiceReferenceXML() results in an authentication fault: - No credentials available for BASIC 'SAP NetWeaver Application Server [D01/100]'@bla:8000 - Unable to sendViaPost to url[foobaz] org.apache.axis2.AxisFault: Transport error: 401 Error: Unauthorized [stacktrace snipped] Setting a breakpoint in BasicAuthenticationReferencePolicyInterceptor#invoke() demonstrates that this interceptor is not called when the copied reference is used. -- Sebastian IDS Scheer Consulting GmbH Geschäftsführer/Managing Directors: Kamyar Niroumand, Ivo Totev Sitz/Registered office: Altenkesseler Straße 17, 66115 Saarbrücken, Germany - Registergericht/Commercial register: Saarbrücken HRB 19681 http://www.softwareag.com
