Introspecting services offered by a Java implementation class without @Service

Hi,

In Java Component Implementation Specification
1.00, we have the following statements:

143 1.2.1.3. Introspecting services
offered by a Java implementation

144 In the cases described below, the
services offered by a Java implementation class may be determined

145 through introspection, eliding the
need to specify them using @Service. The following algorithm is used to

146 determine how services are introspected
from an implementation class:

147 If the interfaces of the SCA services
are not specified with the @Service annotation on the implementation

148 class, it is assumed that all implemented
interfaces that have been annotated as @Remotable are the

149 service interfaces provided by the
component. If none of the implemented interfaces is remotable, then by

150 default the implementation offers
a single service whose type is the implementation class.

What if an interface is annotated with
SCA annotations such as @OneWay or @Callback?

For example:

public class MyServiceImpl implements
Interface1, Interface2 {

}

@Callback(CallbackInterface.class)

public interface Interface1 {

}

@OneWay

public interface Interface2 {

}

By the spec, there is only one service
named MyServiceImpl. But isn't it more natural that we should find two
SCA services: Interface1 and Interface2? Please clarify.

Thanks,

Raymond
