Hi,
It seems that the 1.0 SCA java spec defines an algorithm to introspect the
services provided by a java interface as follows:
1. @Service will be checked first and honored
2. The following is quoted from Java spec 1.2.1.3.
Introspecting services offered by a Java implementation
In the cases described below, the services offered by a Java implementation
class may be determined
through introspection, eliding the need to specify them using @Service. The
following algorithm is used
to determine how services are introspected from an implementation class:
If the interfaces of the SCA services are not specified with the @Service
annotation on the
implementation class, it is assumed that all implemented interfaces that
have been annotated
as @Remotable are the service interfaces provided by the component. If none
of the implemented
interfaces is remotable, then by default the implementation offers a single
service whose type
is the implementation class.
Based on the above, CalculatorServiceImpl is going to have one single
service typed by CalculatorServiceImpl. I believe some of the test cases
assume that all the local interfaces will be taken as the services,
especially if only one interface is implemented by the java class. With the
latest spec, the assumption will be incorrect.
Am I right?
If so, I can change the code to behave this way.
Thanks,
Raymond
