How do I get UUID of newly created Virtual Machine?

[nsyed4]

ManagedObjectReference taskmor = vimPort.createVMTask(vmFolderMor,
                vmConfigSpec, resourcepoolmor, hostmor);
String msg = null;
        String[] opts = new String[] { "info.state", "info.error" };
        String[] opt = new String[] { "state" };
        Object[] result = results.waitForValues(taskmor, opts, opt,
                new Object[][] { new Object[] { TaskInfoState.SUCCESS,
                        TaskInfoState.ERROR } });
        if (result[0].equals(TaskInfoState.SUCCESS)) {
        msg = "Success: VM [" + virtualMachineName+ "] created.";
        } else {
            msg = "Failure: Creating [ " + virtualMachineName + "] ";
      }

I am using JAX-WS client stubs.

The Virtual machine got created. How do I get the UUID of the virtual machine. And how do I know the state of the virtual machine such as virtual machine already exists. It just says it failed.

Thanks for help.
