when i use vimport.createTask, it throws com.sun.xml.internal.ws.fault.ServerSOAPFaultException

[cksincere]

After read API Docs, i still don't know how to use createTask method? 

Is there sample codes?

test code:

    public void main() throws RuntimeFaultFaultMsg, InvalidPropertyFaultMsg {
        //propCollectorRef = serviceContent.getPropertyCollector();
        //getAndPrintInventoryContents();
        //vimPort.generateLogBundlesTask(serviceContent.getDiagnosticManager(),
         //       true,serviceContent.get)
        try{

            System.out.println("task mgr"+serviceContent.getTaskManager().getValue());
            if (serviceContent.getTaskManager() == null) {
                System.out.println("task manager is null");
            }

            TaskInfo tskInfo=vimPort.createTask(serviceContent.getTaskManager(),serviceContent.getTaskManager(),
                    "test","root",
                    true,"","");

            vimPort.setTaskState(tskInfo.getTask(),TaskInfoState.SUCCESS,
                    "success result",tskInfo.getError());
            System.out.println("test task success");
        }catch (Exception e){
            System.out.println("create task error "+e);
            e.printStackTrace();
        }
    }
}
