ant elder commented on TUSCANY-123:
-----------------------------------
This is not fixed. The original issue i think may have been but this exposes
another problem so the ModuleContext locateService still fails.
The problem now appears to be that the object return by locateService does not
implement the expected Java interface. The externalService is using
interface.wsdl so tuscany generates a Java interface class to represent the
WSDL portType. Thats the interface that the proxy returned to the client is
implementing but its not the same as the interface the client is expecting so
the client gets a class cast exception.
I guess what should happen is something like before generating the interface
for the WSDL portType it should check if the client has available a class of
that name and if so use that instead of generating one.
This is the same issue we were discussing on IRC the other day with using
interface.wsdl in a .componentType side file. Can't remember if there's a JIRA
for that, I'll go check and if so link these JIRAs together.
The original description describes how to recreate the problem, if thats not
clear enough here's the patch to make the required change:
