Are you using com.codenameone.io.URL ?
I would recommend avoiding BufferedOutputStream in Codename One as all 
streams are buffered by default in Codename One.
You also need to fetch the result for the request to finish. It won't 
happen until you try to get a response from the server.

I would recommend using APIs like the "Rest" API which is simpler to use 
and doesn't require threading.
