Callback over WS Binding is not functioning various issues
----------------------------------------------------------
Key: TUSCANY-1341
URL: https://issues.apache.org/jira/browse/TUSCANY-1341
Project: Tuscany
Issue Type: Bug
Components: Java SCA Misc Binding Extensions
Affects Versions: Java-SCA-0.90
Reporter: Lou Amodeo
The callback function using WS bindings doesnt appear to be operation. So far
I have :
1) WebServiceBindingProcessor.java
- The resolve() method does not setup the callbackInterface on its
InterfaceContract resulting in NPE.
(i.e. interfaceContract.setCallbackInterface(wsdlCallbackInterface); )

If you set the callbackInterface above and proceeed you hit the following:
2) Axis2ReferenceBindingProvider.java
- I dont think this requires a wire as this provider already knows abouts its
InterfaceContract.
wire is null resulting in a NPE
private Operation findCallbackOperation(RuntimeWire wire) {
/*
InterfaceContract contract = wire.getTarget().getInterfaceContract();
// TODO:
// which
// end? LAA Hack */
InterfaceContract contract = this.getBindingInterfaceContract(); //
LAA hack
List callbackOperations =
contract.getCallbackInterface().getOperations();
if (callbackOperations.size() != 1) {
throw new RuntimeException("Can only handle one callback
operation");
}
Operation callbackOperation = (Operation)callbackOperations.get(0);
return callbackOperation;
}
If you obtain contract directly using getBindingInterfaceContract() you proceed
and get the following:

4) I see this comment in Axis2CallbackInvocationHandler which is not being
executed anyway:
public Axis2CallbackInvocationHandler(MessageFactory messageFactory,
RuntimeWire wire) {
super(messageFactory, false);
this.wire = wire;
}
public Object invoke(Operation operation, Object[] args, LinkedList<URI>
callbackRoutingChain) throws Throwable {
// Object targetAddress = callbackRoutingChain.removeFirst();
// if (targetAddress == null) {
// throw new AssertionError("Popped a null from address from stack");
// }
// //TODO optimize as this is slow in local invocations
// Map<Operation, InvocationChain> sourceCallbackInvocationChains =
// wire.getCallbackInvocationChains();
// InvocationChain chain = sourceCallbackInvocationChains.get(operation);
// chain.g
// TargetInvoker invoker = chain.getTargetInvoker();
// return invoke(chain, invoker, args, null, callbackRoutingChain, null);
throw new UnsupportedOperationException("not yet implemented");
