Socket Error

[Jerry Nicholson]

I'm testing the CN1 socket functionality and am getting this error when I run the project in netbeans:

java.lang.ClassCastException: java.net.Socket cannot be cast to com.codename1.impl.javase.JavaSEPort$SocketImpl

These are the imports:

import com.codename1.io.Socket;
import com.codename1.io.SocketConnection;
import generated.StateMachineBase;
import com.codename1.ui.*;
import com.codename1.ui.events.*;
import com.codename1.ui.util.Resources;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;


try {
                while (isConnected()) {
                    try {
                        pending = is.available();       <------------------------------------------------------------error occurs here
                    } catch (Exception ex) {
                        System.out.println("pending error: " + ex.getMessage());
                        ex.printStackTrace();
                    }
                    if (pending > 0) {
                        size = is.read(arrByte, 0, 1024);
                        if (size == -1) {
                            return;
                        }
                        if (size > 0) {
                            str = new String(arrByte);
                            System.out.println(str);
                        }
                    } else {
                        System.out.println("sleep 5");
                        Thread.sleep(5000);
                    }
                }
            } catch (IOException err) {
                System.out.println("IO " + err.getMessage());
                err.printStackTrace();
            } catch (InterruptedException err) {
                System.out.println("Int " + err.getMessage());
                err.printStackTrace();
            }

Can you please provide the stack trace messages in the console?
Thanks.

Hi,
is this from a server socket (listen)?
If so I think I see the problem and we will fix it for the next update.

[Jerry Nicholson]

Yes, Shai, this is a server socket listen
