Getting error : unexpected element (uri:"", local:"VApp") while composeVapp

Hi All,

While composing a vApp using Java sdk, I am getting the following exception:

SEVERE: null
javax.xml.bind.UnmarshalException: unexpected element (uri:"", local:"VApp"). Expected elements are <{http://schemas.dmtf.org/wbem/wscim/1/cim-schema/2/CIM_ResourceAllocationSettingData}Address.....

This is the code used for creating the Vapp:

try {
            vapp = vdc.composeVapp(createComposeParams( vcloudClient,newvAppName,vAppTemplateRef);
            List<Task> tasks = vapp.getTasks(); //Esception is being raised here.
            if (tasks.size() > 0)
                try {
                    tasks.get(0).waitForTask(0);
                } catch (TimeoutException e) {
                    System.out.println(e.getMessage());
                }
            System.out.println("Compose vApp "+vapp.getResource().getName()+":success");
        } catch(VCloudException e){
            System.out.println("Vcloud Exception "+newvAppName+": "+e.getMessage());
        }

I am attaching the vcloud debug for reference.Can anyone please help me what is this error?

This error is not consistent and also the Vapp is getting created. I have to catch the time of vapp creation which I was not able to do when this exception is generated.Please help me how to capture the time ..

Thanks,

Deepak.
