David, I have no idea. I think this is the line that's failing:
ds = (ClientAccessDataStream) fd_.server_.sendAndReceive(req);
This would imply that either fd_ or fd_.server_ is null. fd_ cannot be
null or it would have failed earlier in the delete() method. In fact,
the delete() method calls fd_.connect(), which is supposed to set the
So the only way I can see this happening is if you somehow lost the
connection for your file and were unable to re-establish it. Are you
doing this delete immediately upon creating the IFS File object?
