Re: [flexcoders] Cant receive socket data

hmmm. I could easily append some bytes and see what happens, but not 
'til Monday when I go back to work.
Thanks!

[flexcoders] Cant receive socket data

[john fisher]

I have a Flex 3.0 app which can connect to a remote socket server, and
send it XML, but nothing happens ( no event fires, no error in debugger)
in Flex when the server returns data. The remote server is appending a
nullbyte to the xml message, and thinks its sending the data.

Ideas?

-
the server code ( perl) snippet:
my $NULLBYTE = pack( 'c', 0 );

if (  $1 eq new ) {
print STDOUT request is: $1 sending xml data\n;
print CONNSOCK $simdata ;
print CONNSOCK $NULLBYTE;
}



the flex code snippet:


| var socket:XMLSocket = *new *XMLSocket();

  socket.addEventListener(Event.CONNECT, connected);
  socket.addEventListener(DataEvent.DATA, dataReceived);

  socket.connect(localhost, 8989);

 
  *private function *connected(event:Event):*void*
{
socket.send(xmldata);
}
  *private function *dataReceived(dataEvent:DataEvent):*void*
{
trace(dataEvent.data);
var xml:XML = *new *XML(dataEvent.data);
}
  

Thanks
John

yikes, please ignore extraneous asterisks in snippet.

this is corrected:

my $NULLBYTE = pack( 'c', 0 );

if (  $1 eq new ) {
print STDOUT request is: $1 sending xml data\n;
print CONNSOCK $simdata ;

}



the flex code snippet:


 var socket:XMLSocket = new XMLSocket();

  socket.addEventListener(Event.CONNECT, connected);
  socket.addEventListener(DataEvent.DATA, dataReceived);

  socket.connect(localhost, 8989);

{
socket.send(xmldata);
}
  private function dataReceived(dataEvent:DataEvent):void
{
trace(dataEvent.data);
var xml:XML = new XML(dataEvent.data);
}
  

Thanks

You are an optimist: you are not listening for 
flash.events.IOErrorEvent.IO_ERROR or 
flash.events.SecurityErrorEvent.SECURITY_ERROR from the XMLSocket.

Re: [flexcoders] Cant receive socket data

[john fisher]

Thanks - but I added this code and no change. The events don't fire.

socket = new XMLSocket();
configureListeners(socket);

 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);
}
etc etc etc copied from

More debugging:

If I send
connect,  request data (a short XML text which the server is looking
for),  then connect again,
The data comes through.

Note: I am watching in a packet sniffer and I never see the policy file
come across any port, though I am able to connect.

Note2: if I remove the nullbyte from the perl code no data ever appears.
