import javax.swing.ImageIcon;
import javax.swing.JPanel;
import javax.swing.JOptionPane;
import javax.swing.JFrame;

class ClientScreenReciever extends Thread {

private ObjectInputStream cObjectInputStream = null;
private JPanel cPanel = null;
private boolean continueLoop = true;

public ClientScreenReciever(ObjectInputStream ois, JPanel p) {
cObjectInputStream = ois;
cPanel = p;
//start the thread and thus call the run method
start();
}

public void run(){

try {

//Read screenshots of the client then draw them
while(continueLoop){
//Recieve client screenshot and resize it to the current panel size
ImageIcon imageIcon = (ImageIcon) cObjectInputStream.readObject();
System.out.println("New image recieved");
Image image = imageIcon.getImage();
image = image.getScaledInstance(cPanel.getWidth(),cPanel.g etHeight()
,Image.SCALE_FAST);
//Draw the recieved screenshot
Graphics graphics = cPanel.getGraphics();
graphics.drawImage(image, 0, 0, cPanel.getWidth(),cPanel.getHeight(),cPanel);
}
} catch (IOException ex) {
ex.printStackTrace();
} catch(ClassNotFoundException ex){
ex.printStackTrace();
}
JOptionPane.showMessageDialog(cPanel,"Client DISConnected");
}

You're running different versions of the Java virtual machine. The serial ids of a built-in class differ (as the Exception message told you). Make your clients and server run the same Java version.

Thank you Mr.jos!
i installed jdk.6 & 7 also in the both systems..,
running by using JDK.6 with netbeas IDE 6.9
what ca i do now..,

[JosAH]

I both your server and clients are running the same Java version, try to run your program again and see ... (make sure you recompile your program against that latest Java version).

kind regards,

Jos

Thanks Mr.Jos!

Thank to Jesus..,

Good to read that it runs now; the error message was trying to tell you what was wrong: the serial version ids were different so there were two different versions of one and the same class; so your client(s) and server were running different versions of Java. Learning how to read error messages pays off ;-)

kind regards,

Jos
