Program to transfer files from one server to another and displaying a progress bar for each transfer

Program to transfer files from one server to another and displaying a progress bar for each transfer

i have written a java code to transfer files from one server to another using the concept of socket programming. now in the same code i also want to check for the network connection availability before each file is transferred. i also want that the files transferred should be transferred according to their numerical sequence. And while the files are being transferred the transfer progress of each file i.e the progress percentage bar should also be visible on the screen.
i will really appreciate if someone can help me with the code. i am posting the code i have written for file transfer.
ClientMain.java
public class ClientMain {
    private DirectoryTxr transmitter = null;
    Socket clientSocket = null;
    private boolean connectedStatus = false;
    private String ipAddress;
    String srcPath = null;
    String dstPath = "";
    public ClientMain() {

    }

    public void setIpAddress(String ip) {
        this.ipAddress = ip;
    }

    public void setSrcPath(String path) {
        this.srcPath = path;
    }

    public void setDstPath(String path) {
        this.dstPath = path;
    }

    private void createConnection() {
        Runnable connectRunnable = new Runnable() {
            public void run() {
                while (!connectedStatus) {
                    try {
                        clientSocket = new Socket(ipAddress, 3339);
                        connectedStatus = true;
                        transmitter = new DirectoryTxr(clientSocket, srcPath, dstPath);
                    } catch (IOException io) {
                        io.printStackTrace();
                    }
                }

            }
        };
        Thread connectionThread = new Thread(connectRunnable);
        connectionThread.start();
    }

    public static void main(String[] args) {
        ClientMain main = new ClientMain();
        main.setIpAddress("10.6.3.92");
        main.setSrcPath("C:/chirashree");
        main.setDstPath("C:/jp");
        main.createConnection();

    }
}
