> 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
