Servlet接收手机传输过来的数据出现问题，急请高手帮忙解决。
手机发生代码：
hc   =   (HttpConnection)Connector.open(SERVICE_ADDRESS);
hc.setRequestMethod(HttpConnection.POST);
hc.setRequestProperty( "Content-Type ",   "application/x-www-form-urlencoded ");
DataOutputStream   dos=hc.openDataOutputStream();
dos.writeUTF(card.toString());
dos.flush();
dos.close();

Servlet接受代码：
DataInputStream   din=new   DataInputStream(request.getInputStream());
System.out.println(din.readUTF());

以上代码在本地机器上测试没问题。
就是部署到服务器上以后，无论如何Servlet老是接受不到手机传输过来的数据。
还请那位大虾指教下，明天要交活了，急啊

我想问的是 你说的本机能测试通过 而到服务器上不能执行
