Servlets 如何将数据从blackberry发送到servlet

我使用下面的代码将数据发送到servlet

     HttpConnection c = (HttpConnection)Connector.open("http://localhost:8585/resposweb/resposweb?action=create_order;deviceside=true");

                            c.setRequestMethod(HttpConnection.POST);
                            c.setRequestProperty("If-Modified-Since", "29 Oct 1999 19:43:31 GMT");
                            c.setRequestProperty("User-Agent", "Profile/MIDP-2.0 Configuration/CLDC-1.0");
                            c.setRequestProperty("Content-Language", "en-US");
                            os = (DataOutputStream)c.openDataOutputStream();

                            //byte[] res = net.rim.device.api.system.GPRSInfo.getIMEI();
                            os.writeUTF(ViewItems.isNewOrder());
                            os.writeUTF(OrderDetails.getOrderDtlAsString());
                            os.flush();    
                           os.close();

在服务器端，我使用下面的代码从blackberry接收数据

 DataInputStream in = new DataInputStream((InputStream)request.getInputStream());
 String orderType = in.readUTF().trim();
 String mobdata = in.readUTF().trim();

但在服务器端，我得到以下例外

java.io.EOFException

有人能告诉我如何将数据发送到servlet（java）吗

使用HttpConnection。获取方法可在打开连接时通过url发送数据。
