tcp server applet

[rareseu]

Hy guys ! i'm having a problem getting my tcp server applet on it's feet, the problem is that it doesn't get past instantiating a socket, if i instatiate it with port nr 80 it throws an exception ( Address already in use: JVM_Bind ), with other ports it just locks up at the "binding port" part

    ServerSocket server;
    int port= Integer.parseInt(portNumber.getText());//port number's a text field
    status.setText("Starting server..\\n");//status is a text area

    try {
        status.append("Binding to port " + port + ", please wait  ...\\n");
        server = new ServerSocket(port);
    } catch (IOException ioe) {
        status.append("EROARE la creearea socketului\\nEXCEPTIE:

"+ioe.getMessage()+"\n");
return;
}

does anybody have a clue why this happens?

I couldn't say why a port might lock up, but if you're using windows you could run the "netstat -a -b" command with arguments to determine if the ports you are selecting are in use. The -b parameter will also tell you what process is using the port in question. At a minimum, that will tell you if a port you are trying to use is available or not. If you have an appserver installed and running, (or even skype), one of them may be using port 80.

You might have something else on port 80? This is the main port used by HTTP, so if you've got another web-service it may well be in use. Try running it up pointing to a DIFFERENT port and see what happens.

[/quote] allready tried , it locks up at the ServerSocket instantiation, and starting today it lock up on 80 too, i have absolutelly no clue what i'm doing wrong
