While I fix the previous error (register a SCA node without code) I am writing the composite and componentType files. I have chose the first option. But I need you check the content if it is possible.

Can I remove these files from TestService bundle and put the TestService´s bundle.componentType in the Calculator bundle. You said "Alternatively, you have place the file as OSGI-INF/sca/<bundleSymbolicName>/bundle.componentType in the calculator bundle." Do you mean I can copy TestService´s bundle.componentType into a CalculatorService bundle?
