Subject: [ISSUE 59] SCA Spring C & I specification does not state what happens whena Bean exposed as a service implements mutliple interfaces - PROPOSAL
- From: Mike Edwards <mike_edwards@uk.ibm.com>
- To: "OASIS Java" <sca-j@lists.oasis-open.org>

Folks,
The following is a proposal to RESOLVE
Java Issue 59.
This proposal is DEPENDENT on the resolution
of the issue raised to add a names attribute to the @Service
annotation.
Proposal:
------------------------------------------------
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 EITHER:
a) by giving each service an explicit
unique name using the @Service SCA annotation within the bean class
OR
b) where the @Service annotation is
not present, each service is given the name "beanName.serviceName",
where beanName is the name of the Bean
in the application context and serviceName is the name of the service
determined implicitly from the name
of the interface (without the package name).
In case a) it is the responsibility
of the programmer to ensure that the service names specified in the @Service
annotation do not clash with any other
service names in the same application context.
