Please Login to Remove!

Hello,

I write a program to connect the blackberry with laptop with socket

try{
add(new RichTextField("Start to connection ..."));
SocketConnection sc = (SocketConnection)Connector.open("socket://134.91.99.178:4000;deviceside=true;interface=wifi" , Connector.READ_WRITE, false);

DataOutputStream os = sc.openDataOutputStream();

os.writeUTF("please show the position of the tag");
os.flush();
os.close();
sc.close();
}

catch (IOException e)
{
e.printStackTrace();
System.out.println("the server is not lisenning");
}

on laptop side, i write a program which open a server socket to listen. but the string "please show the position of the tag" cannot be correctly displayed on the laptop side, evertime it displays "NULL".
