I am trying to create a server socket on my BB 8120 v4.3.0.115 while using only WiFi (no sim card in the device).
For that I tried the sample given in the documentation under Interface ServerSocketConnection.
I modified theConnector.open call by passing it Connector.open("socket://:15234";interface=wifi);
I am using JDE 4.3.0.

Meanwhile I also checked the SocketDemo example provided with the api. It works for Computer (server) -- BB device (client) configuration using WiFi on the same device.

Seems that the serverSocket does get created on the device, just that no communication takes place.
It keeps on waiting on the call to acceptAndOpen().
I tried connecting to the serverSocket by doing -- "telnet 15234" from the computer command prompt.
I spawned a new thread and have the following code in the run():

String url = "socket://:15234;interface=wifi"; scn = (ServerSocketConnection) Connector.open(url); System.out.println("server socket conn = " + scn.toString()); System.out.println("address = " + scn.getLocalAddress()); System.out.println("port = " + scn.getLocalPort()); System.out.println("wait for an incoming connection"); // Wait for a connection. sc = (SocketConnection) scn.acceptAndOpen();




I see the following output:


server socket conn = net.rim.device.cldc.io.tcp.TcpServerSocketConnection@3bc630f
address =
port = 15234
wait for an incoming connection


Am I missing something here?

Re: ServerSocketConnection


may be you should try this,


String url = "socket://;deviceside=true;interface=wifi";
scn = (ServerSocketConnection) Connector.open(url);


If this works mark it as SOLUTION!!

Re: ServerSocketConnection



String url = "socket://;deviceside=true;interface=wifi";
scn = (ServerSocketConnection) Connector.open(url);





Your original code is correct. The code above will create a client connection to the nominated address. The code below should work, however there are considerations about the devices you might use. If you are using a simulator before OS 5.0 you will probably need to drop the interface=wifi part.


String url = "socket://:15234;deviceside=true;interface=wifi";

Re: ServerSocketConnection

I was not aware that it was possible to set the IP Address of a BlackBerry device, except possibly the WiFi Address, but even then it would have to match the network in which it was connected.


Are you sure this code is correct?
