Subject: [NEW ISSUE] SCA Spring C & I specification does not state what happens whena Bean exposed as a service implements mutliple interfaces

Raiser:                Mike Edwards

Target:                 sca-springci-draft-20070926.doc


It is possible for a Spring Bean in a Spring Application context to implement more than one interface, which may in turn be exposed via SCA as a service.

The specification does not say how such a Bean should be exposed as a service - leaving any runtime implementation to make a guess.


Where a Spring Bean in a Spring Application context implements more than one interface which is either explicitly or implicitly exposed as a service according
to SCA Java rules:

- Each interface is exposed as a separate service
- The name of each service must be unique.  Uniqueness is achieved by giving each service is the name "beanName.serviceName", where beanName is the
name of the Bean in the application context and serviceName is the name of the service, where the service name is EITHER given explicitly via an @Service
annotation in the code OR determined implicitly from the name of the interface.
