WSAS Clustering: context replication failure with in-only MEP
-------------------------------------------------------------

                 Key: WSAS-244
                 URL: http://www.wso2.org/jira/browse/WSAS-244
             Project: WSO2 WSAS-Java
          Issue Type: Bug
    Affects Versions: Nightly
         Environment: winxp, jdk15
            Reporter: Charitha Kankanamge

            Priority: Critical


I always get the following exception when invoking a service which includes in-only mep through a cluster with 2 nodes. 

ERROR [2007-05-24 16:44:25,578]  Exception occurred while trying to invoke service method getResult java.lang.reflect.InvocationTargetException

Caused by: java.lang.NullPointerException
        at mysessionservice.getResult(mysessionservice.java:19)

Steps to reproduce:
================
1. Set up a wsas cluster with 2 nodes
2. Deploy the following service in those 2 nodes

public class mysessionservice {
	 public void multiply(int x, int y){
		 System.out.println("Setting context!!!!!");
		 ConfigurationContext configContext =
             MessageContext.getCurrentMessageContext().getConfigurationContext();
		 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
