After today's call we have three possible
approaches to resolving this issue: Treating a name conflict as an error,
having different names define multiple services or name from @Service overrides
name from @WebService.
Here is a starting list of the advantages
and disadvantages of each...
Treating a name conflict as an error:
Advantages
No surprise services
defined
No need to try
and infer developer's intentions
Disadvantages
Forces a developer
to make source changes to fix error
Removes developer's
control over the SCA service name (i.e. is forced to use name from @WebService)
Different names define multiple services:
Advantages
Allows for different
services with different sets of intents
No need to try
and infer developer's intentions
Generalizes to
any service name mismatch scenarios
Disadvantages
Potential developer
surprise at additional service(s) being created
Name from @Service overrides name from
@WebService:
Advantages
Keeps developer's
control over the SCA service name
Idea is that @Service
was added for a reason
Disadvantages
Does not address
conflicting @WebService names (@WebService on both interface and implementation
class)
Potential confusion
if a client is using a WSDL document derived, using JAX-WS tools, from
the @WebService annotation (i.e. WSDL portName and SCA service name would
not match)

| [sca-j] ISSUE 212: @Service vs. @WebService
name conflicts |
I have uploaded a proposal for Issue
212 base on the discussion in Monday's call [1]. It includes an additional
normative statement in the CAA spec, with a corresponding Test Assertion
and TestCase and comments in the CI spec including a reference to the CAA
spec. The bulk of the test artifacts for the test case are available
[2]. The updated version of tuscany-oasis-sca-tests-errors.properties
is not ready yet. Tuscany needs to add a test for this mismatch and
until that is done I do not know what the error message will be.
