JavaME GPRS

Question

Hi!
I have a problem sending data with my phone over GPRS to my server! When I run my code on emulator (netbeans) it runs OK! But when i try it for real, the phone connects via GPRS, but no data is sent. Here is my code if someone could help! Thanks
SERVER:
ServerSocket server = new ServerSocket(11111);
Socket socket = server.accept();
DataInputStream in = new DataInputStream(socket.getInputStream());
byte[] data = new byte[8];
while (in.read(data,0,8)!=-1) {
                   System.out.println(in.read());
CLIENT(PHONE):
DataOutputStream output= new DataOutputStream(Connector.openDataOutputStream("socket://(serverip):11111"));
byte[] data = new byte[8];
                 data[0]=3;data[1]=63;data[2]=63;data[3]=37;data[4]=38;data[5]=30;data[6]=13;data[7]=23;
                 while(true)
                    output.write(data,0,8);Thanks

Answer 1

i wud like to know as to what are u doing to create a
GPRS connection?? http connection or a socket as is
shown above. sorry if this sounds naive but i need to
know this.Just connect to socket or http url, and the phone will do the rest if you configured it correctly. You cannot setup the connection via MIDP.
also do u know as to how i can get the packet size
that is sent/received using the GPRS signal.It is not possible to get the max MTU in MIDP.
