What is the way to read from a socket in Blackberry?

I have used the following code to read but it does not reads .

for(int i=0;i<length;++i)
{
input[i] = ((char)in.read());

System.out.println("OUPUT : " +input[i]);

}

It gets stalled.

I tried to use InpuStream.read() but it too does'nt work.

Any Suggestions....

This is the code snipit from the OS 6 API:

   SocketConnection sc = (SocketConnection)
                         Connector.open("socket://host.com:79");
   sc.setSocketOption(SocketConnection.LINGER, 5);

   InputStream is  = sc.openInputStream();
   OutputStream os = sc.openOutputStream();

   os.write("\r\n".getBytes());
   int ch = 0;
   while(ch != -1) {
       ch = is.read();
   }

   is.close();
   os.close();
   sc.close();

Any code that may block (such as socket reads or writes) must be run on a thread separate from the event thread.

Yes , that was perfect .
I was trying to create a server socket in BB
Any ideas....

If you leave out the host name part of the URI in the Connector.open() will return a ServerSocketConnection. You can then use acceptAndOpen to receive connections. The problem is for other systems finding your IP address and connecting. It should work on Wi-Fi, and I have sent UDP packets between BlackBerries on the same carrier, but (at least with my carrier) the phones end up NATed behind the carier's firewall.

Hi,
I have to create a server socket for accepting connections. For that how do i get the ip address of the phone (simulator) . I have used the following code to retrieve the ip.
{
scn = (ServerSocketConnection)Connector.open("socket://:1234");
System.out.println("IP Address----" + scn.getLocalAddress().toString()+"\n");
}

But the value if ip its showing blank????? i.e. IP Address---- blank

Without the ip connec. can't be created......

Not all methods of connection are actually implemented by TCP/IP stacks on the phone so there is no IP address associated with the phone in that case. You will need to select a connectiion method that supports an IP address. Not all the connections that support IP addresses are available for the simulator, in fact I'm not sure any are.

Code Snippet

public void run() {

// Create the server listening socket for port 1234
try{
ServerSocketConnection scn = (ServerSocketConnection)Connector.open("socket://:1234");
// Wait for a connection.
SocketConnection sc = (SocketConnection) scn.acceptAndOpen();

// Set application specific hints on the socket.
sc.setSocketOption(SocketConnection.DELAY, 0);
sc.setSocketOption(SocketConnection.LINGER, 0);
sc.setSocketOption(SocketConnection.KEEPALIVE, 0);
sc.setSocketOption(SocketConnection.RCVBUF, 128);
sc.setSocketOption(SocketConnection.SNDBUF, 128)

// Get the input stream of the connection.
DataInputStream is = sc.openDataInputStream();

// Get the output stream of the connection.
DataOutputStream os = sc.openDataOutputStream();
} catch (Exception e) {
System.out.println(e.toString());
}
}
}
