A useful debugging aid would be to print out the generated composites that both your nodes will run. You can get that by pointing your browser at URI that the nodes use to load their composite, for example, http://localhost:9990/composite-resolved/composite:node_compA;http://sample;Node_compA_comp Take a look in there and see if the reference binding uris match the service binding uris Regards Simon
