Impossibility to connect to a java server with AS3

Question

I'm having trouble with a XMLSocket script in AS3. I have a java server and i'm trying to send a XML data, but the server isn't recieving anything. The most suprising is that my script worked very well a month ago, and now my IOError listener returns me :

"Error #2031: Socket error. URL: 127.0.0.1 at test() at Client_fla::MainTimeline/frame1()"

and my SecurityError listener :

"Error #2048: Security Sandbox violation : file:///C|/Documents%20and%20Settings/Zeph/Bureau/Client.swf cannot load data from 127.0.0.1:18000. at test() at Client_fla::MainTimeline/frame1()"

I tried to change IP, I tried on another computer, I tried to pull a former version of my script, which was unchanged, with no result.

I just can't understand why it stopped working like this. Here is my script :

package
{

    import flash.net.XMLSocket;
    import flash.events.*;
    import flash.display.MovieClip;

    public class test extends MovieClip 
    {

        public function test()
        {
            trace("pouet");
            var xmlsock:XMLSocket = new XMLSocket(); 
            xmlsock.connect("127.0.0.1", 18000);
            var xmlFormattedData = new XML('<message pseudo="Nix" value="Coucou !"/>'); 
            xmlsock.send(xmlFormattedData);
            xmlsock.addEventListener(DataEvent.DATA, onData);
            xmlsock.addEventListener(IOErrorEvent.IO_ERROR, ioerror);
            xmlsock.addEventListener(SecurityErrorEvent.SECURITY_ERROR, secuerror);
            xmlsock.send(xmlFormattedData);

        }

        private function onData(event:DataEvent):void 
        { 
            trace("[" + event.type + "] " + event.data); 
        }


        private function ioerror(event:IOErrorEvent):void 
        { 
        trace(event);
        }

        private function secuerror(event:SecurityErrorEvent):void 
        { 
        trace(event);
        }

    }

}

I'm getting mad with this, does anyone have an idea?

Thanks for reading!

Answer 1

the error suggests, that you are running a flash application from your local file system and this application wants to make a network request (to your java server).

This is not allowed by default. You can do one of two things:

• Update your Global Security Settings in your flash player (right click, advanced settings, global security settings, then set the flash file or the whole folder to be allowed to do network requests)

• Run your flash application from a webserver (and make sure, that a crossdomain.xml is in place on the java server).
