Mark Combellack commented on TUSCANY-2180:
------------------------------------------
I've raised this scenario with the OASIS SCA Assembly TC to see if it is valid
to do this. The replies basically said that yes, it is valid.

> Cannot invoke method on Service that implements multiple @Remotable
> interfaces with methods of the same name

> Key: TUSCANY-2180
> URL: https://issues.apache.org/jira/browse/TUSCANY-2180
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Core Runtime
> Affects Versions: Java-SCA-1.1
> Environment: SVN Revision 643322
> Linux
> Reporter: Mark Combellack
> Assignee: Mark Combellack
> Fix For: Java-SCA-Next
>
>
> When a Component implementation class implements multiple @Remotable
> interfaces which have methods with the same name, it is not possible to
> invoke the duplicate method name on the second Remotable interrface.
> Consider the following example:
> I have two @Remotable services as defined by the following Java interfaces:
> @Remotable
> public interface LocalTimeService {
> Date getCurrentTime();
> }
> @Remotable
> public interface WorldTimeService {
> Date getCurrentTime(String timeZone);
> }
> I have a single Java Component that implements both of these @Remotable
> Interfaces:
> @Service(interfaces = {LocalTimeService.class, WorldTimeService.class})
> public void class TimeServiceImpl implements LocalTimeService,
> WorldTimeService {
> public Date getCurrentTime() {
> // Code not shown
> }
> public Date getCurrentTime(String timeZone) {
> // Code not shown
> }
> }
> If I invoke getCurrentTime(), the code will work
> If I invoke getCurrentTime("GMT"), the code will fail. The stack trace is:
> java.lang.IllegalArgumentException: argument type mismatch
