Hi, i am using NetBeans IDE 6.0.1 and i created a server project and a client project, first i run the server that listens to the port "8221" and waits for clients accessing that port, and when i run the client that accesses the server at port "8221" the IDE throws this exception
"Exception in thread "main" java.net.BindException: Address already in use: JVM_Bind
at java.net.PlainSocketImpl.socketBind(Native Method)"
By the way, i checked for any process using the same port in the command window by typing "netstat -a" and i didn't find any.
The server code: -
try {
-
ServerSocket server = new ServerSocket(8221);
-
System.out.println("Waiting for clients\n");
-
Socket connection = server.accept();
-
ObjectInputStream input = new ObjectInputStream(connection.getInputStream());
-
ObjectOutputStream output = new ObjectOutputStream(connection.getOutputStream());
-
StringBuffer buff = new StringBuffer();
-
do {
-
int c = 0;
-
while (((c = input.read()) != '\n') || ((c = input.read()) != -1)) {
-
buff.append(c);
-
}
-
msg = buff.toString();
-
} while (msg != "Exit");
-
System.out.println(msg);
-
} catch (IOException ex) {
-
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
-
}
-
The client code: -
try {
-
-
Socket client = new Socket(InetAddress.getLocalHost(),8221);
-
//Socket client = new Socket("192.168.1.18",8221);
-
ObjectInputStream input = new ObjectInputStream(client.getInputStream());
-
ObjectOutputStream output = new ObjectOutputStream(client.getOutputStream());
-
String msg = "Hello Exit";
-
output.writeBytes(msg);
-
// StringBuffer buff = new StringBuffer();
-
// do {
-
// int c = 0;
-
// while (((c = input.read()) != '\n') || ((c = input.read()) != -1)) {
-
// buff.append(c);
-
// }
-
// msg = buff.toString();
-
// } while (msg != "Exit");
-
} catch (IOException ex) {
-
// Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
-
System.out.println(ex);
-
}
-
Thanks.
