WS binding: ClassCastException:

Key: TUSCANY-4000
URL: https://issues.apache.org/jira/browse/TUSCANY-4000
Project: Tuscany
Issue Type: Bug
Components: Java SCA Axis Binding Extension
Affects Versions: Java-SCA-2.0-Beta3
Reporter: Rashmi Hunt
WS Binding reference with WSDL interface with a WSDL callback interface
<---invoking---> WS Binding Service with WSDL interface with a WSDL callback
interface
throws ClassCastException when Tuscany tries to cast WSDLInterfaceImpl to
JavaInterface
at JavaImplementationInvoker.invoke() method, at
(JavaInterface)interfaze.getCallbackInterface()
// If there is a callback interface and the implementation is
stateless, we need to
// inject callbacks at invocation time. For Composite scope, this
has already been done.
if (( interfaze.getCallbackInterface() != null ) &&
(scopeContainer.getScope().equals(Scope.STATELESS))){
injectCallbacks(wrapper,
(JavaInterface)interfaze.getCallbackInterface());
}
This exception occurs when Web Service message reaches service implementation
which eventually invokes
JavaImplementationInvoker.invoke()
The above code is assuming that interfaze.getCallbackInterface() will return
instance of JavaInterface.
What if the callback interface on both service and reference are using WSDL
interface?
Shouldn't above logic take care of WSDL interface case?
