Afkham Azeez resolved WSAS-244.
-------------------------------
Fix Version/s: Nightly
Resolution: Fixed
Fixed. This was due to the adding of the ClusteringPhase after the DispatchPhase in the global InFlow. All phases added after the DispatchPhase in the global InFlow have no effect.

> configContext.setProperty("VALUE", new Integer(x * y));
>
> }
> public int getResult(){
> System.out.println("Getting results!!!!!");
> ConfigurationContext configContext =
> MessageContext.getCurrentMessageContext().getConfigurationContext();
>
> return ((Integer) configContext.getProperty("VALUE")).intValue();
> }
> 3. Generate stubs and write a client as follows.
> public class sessionawareclient {
> public static void main(String[] args) throws AxisFault {
>
> MysessionservicemysessionserviceSOAP11Port_http1Stub stub1 = new MysessionservicemysessionserviceSOAP11Port_http1Stub("http://10.100.1.244:9762/services/mysessionservice");
> MysessionservicemysessionserviceSOAP11Port_http1Stub.Multiply request = new MysessionservicemysessionserviceSOAP11Port_http1Stub.Multiply();
> request.setX(9);
> request.setY(5);
> try {
> stub1.multiply(request);
> } catch (RemoteException e1) {
> // TODO Auto-generated catch block
> e1.printStackTrace();
> }
>
> try {
> Thread.sleep(200);
> } catch (InterruptedException e1) {
> // TODO Auto-generated catch block
> e1.printStackTrace();
> }

> MysessionservicemysessionserviceSOAP11Port_http1Stub stub2 = new MysessionservicemysessionserviceSOAP11Port_http1Stub("http://10.100.1.58:9762/services/mysessionservice");
> try {
> System.out.println("Getting results from node2");
> MysessionservicemysessionserviceSOAP11Port_http1Stub.GetResultResponse res = stub2.getResult();
> System.out.println(res.get_return());
> } catch (RemoteException e) {
> // TODO Auto-generated catch block
> e.printStackTrace();
> }
> }
> }
> 4. Run the client
