AS3/AIR 1.5 -SIMPLE- Socket Server with Java
I was just wondering if there was any reason this wasn't working. Basically I'm writing an application (let's call it a game so I can keep this thread here because it probably would be useful for games too) and I originally wanted to use FSCommand to launch video files. Unfortunately, until AIR 2.0 this is impossible and you need an external process running so, knowing java can launch files, I decided to write a simple socket server to pass the file path to and have Java execute it for me. Here's the AppSocket class:
Code:
package com.hsg.util {
import flash.display.Sprite;
import flash.events.*;
import flash.net.XMLSocket;
public class AppSocket extends Sprite {
private var hostName:String = "localhost";
private var port:uint = 8080;
private var socket:XMLSocket;
private var sendData:String;
public function AppSocket(data:String) {
sendData = data;
socket = new XMLSocket();
configureListeners(socket);
socket.connect(hostName, port);
}
public function send():void {
socket.send(sendData);
}
private function configureListeners(dispatcher:IEventDispatcher):void {
dispatcher.addEventListener(Event.CLOSE, closeHandler);
dispatcher.addEventListener(Event.CONNECT, connectHandler);
dispatcher.addEventListener(DataEvent.DATA, dataHandler);
dispatcher.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);
dispatcher.addEventListener(ProgressEvent.PROGRESS, progressHandler);
dispatcher.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);
}
private function closeHandler(event:Event):void {
trace("closeHandler: " + event);
}
private function connectHandler(event:Event):void {
trace("connectHandler: " + event);
}
private function dataHandler(event:DataEvent):void {
trace("dataHandler: " + event);
}
private function ioErrorHandler(event:IOErrorEvent):void {
trace("ioErrorHandler: " + event);
}
private function progressHandler(event:ProgressEvent):void {
trace("progressHandler loaded:" + event.bytesLoaded + " total: " + event.bytesTotal);
}
private function securityErrorHandler(event:SecurityErrorEvent):void {
trace("securityErrorHandler: " + event);
}
}
}
And here is my single file Java socket server:
Code:
import java.io.*;
import java.net.*;
public class simpleServer
{
public static void main(String args[])
{
// Message terminator
char EOF = (char)0x00;
try
{
// create a serverSocket connection on port 9999
ServerSocket s = new ServerSocket(8080);
System.out.println("Server started. Waiting for connections...");
// wait for incoming connections
Socket incoming = s.accept();
BufferedReader data_in = new BufferedReader(
new InputStreamReader(incoming.getInputStream()));
PrintWriter data_out = new PrintWriter(incoming.getOutputStream());
data_out.println("Welcome! type EXIT to quit." + EOF);
data_out.flush();
boolean quit = false;
// Waits for the EXIT command
while (!quit)
{
String msg = data_in.readLine();
try {
System.out.println("Executing: " + msg);
Process p = Runtime.getRuntime().exec(msg);
} catch (Exception err) {
System.out.println("Error.");
}
if (msg == null) quit = true;
if (!msg.trim().equals("EXIT"))
{
data_out.println("You sayed: <b>"+msg.trim()+"</b>"+EOF);
data_out.flush();
}
else
{
quit = true;
}
}
}
catch (Exception e)
{
System.out.println("Connection lost");
}
}
}
And here's how I call it:
Code:
private function launchFile(path:String) {
var sock:AppSocket = new AppSocket(path);
sock.addEventListener(Event.CONNECT, blah);
}
private function blah(de:DataEvent) {
trace("TEST DATA BEING SENT");
de.target.send("TEST DATA");
}
Now, it will show the path in java, but my problem is that it takes something like 10-30 seconds for Java to finally display the message it received. Is there a way to speed this up? Also, it's failing to execute the file. Flash does receive the message "Welcome! Type EXIT to quit.". It will trace out the path I give (i.e C:\Users\Public\Videos\vid.avi) but it never executes. After it displays the path it immediately terminates the java program. Output:
Code:
Server started. Waiting for connections...
Executing: C:\Users\Public\Videos\vid.aviError. java.lang.NullPointerException
Connection lost
Process completed.
If anyone could figure what I'm doing wrong here, I'd much appreciate it. This app is so far behind schedule it's not even funny because I didn't realize they changed FSCommand capability in AS3/AIR. :yikes:
I am working with Adobe CS4 Professional, AIR 1.5, AS3, on Windows 7.
