I have a java server which is using TCP and sockets to connect to an Android application (the client) and sends strings (currently taken in from a scanner object) which are then displayed as notifications by the client.
heres the Server code without all the imports.
public class Server {
// define our Main method
public static void main(String[] args) throws IOException {
// set up our Server Socket, set to null for the moment.
ServerSocket serverSocket = null;
boolean isConnected = false;
// Lets try and instantiate our server and define a port number .
try {
serverSocket = new ServerSocket(6789);
isConnected = true;
System.out.println("*** I am the Server ***\n");
// make sure to always catch any exceptions that may occur.
} catch (IOException e) {
// always print error to "System.err"
System.err.println("Could not listen on port: 6789.");
System.exit(1);
}
// We always want to check for connection from Clients, so lets define
// a for ever loop.
for (;;) {
// define a local client socket
Socket clientSocket = null;
// lets see if there are any connections and if so, accept it.
try {
clientSocket = serverSocket.accept();
// don't forget to catch your exceptions
} catch (IOException e) {
System.err.println("Accept failed.");
System.exit(1);
}
// Prepare the input & output streams via the client socket.
// fancy way of saying we want to be able to read and write data to
// the client socket that is connected.
BufferedReader inFromClient = new BufferedReader(new InputStreamReader(
clientSocket.getInputStream()));
PrintWriter outToClient = new PrintWriter(clientSocket.getOutputStream(),
true);
while (isConnected) {
// read a sentence from client
String hiFromClient = inFromClient.readLine();
// Set up the logging system and timestamp and log message.
Calendar currentDate = Calendar.getInstance();
SimpleDateFormat formatter=
new SimpleDateFormat("yyyy/MMM/dd HH:mm:ss");
String dateNow = formatter.format(currentDate.getTime());
try{
// Create file
File fstream = new File("log.txt");
FileWriter out = new FileWriter(fstream);
out.write(hiFromClient + " " + dateNow);
//Close the output stream
out.close();
} catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
// Print the client sentence to the screen
System.out.println("The Client said: "+hiFromClient);
// Reply to the client
Scanner scanner = new Scanner(System.in);
String sentence = scanner.nextLine();
outToClient.println(sentence );
System.out.println("The Server said: " + sentence);
}
// always remember to close all connections.
inFromClient.close(); // the reader
outToClient.close(); // the writer
clientSocket.close(); // and the client socket
}
}}
Growl uses port 23053 for notification forwarding. What i am hoping to do is to listen in on 23053 and send anything in from that as a string to the client connected at 6789. Sadly Growl binds the port number so a new Socket connection cant be made.
Any one have any ideas on how i could get notifications from the port number growl uses or even just use growl as the server for the client itself (the client's code is very similar to the servers by the way just using Socket instead of ServerSocket)
Any help on this would be greatly appreciated, its wrecking my brain
All the best,
Patrick.
