Flash Builder 4.5 SOAP call for images using Base64 Encoding

Question

I am trying to load some image meta data in a flash builder mobile application by making a SOAP call to .Net service. I am able to test the web service successfully using a .Net console application. However when I make the call from flash builder mobile client I get a null result. What am I doing wrong? I am using SOAP 1.1 ByteArray didn't work for Flash builder. So converted the ByteArray to Base64 format and tried to obtain result that way. Both ways worked from a .Net Client but not working from Flash mobile.
Here is the code
<fx:Script>
        <![CDATA[          
            import mx.graphics.ImageSnapshot;
            import mx.graphics.codec.JPEGEncoder;
            import mx.graphics.codec.PNGEncoder;
            import mx.rpc.AsyncToken;
            import mx.utils.Base64Encoder;         
            import services.exifimagemetadata1.ExifImageMetaData1;         
            import spark.components.Image;     
            public var metaData:ExifImageMetaData1 = new ExifImageMetaData1();         
            public var imageBytes:ByteArray = new ByteArray();
            public var gpsData:String;
    private function getBase64EncodedImage():String
                var myEncoder:Base64Encoder = new Base64Encoder();
                myEncoder.encodeBytes(getImageBytes());            
                var image64BitText:String = myEncoder.toString();                          
                return image64BitText;
    public function GetMetaDataFromExif():void{
                var imageToken:AsyncToken = metaData.GetExifBase64Data(getBase64EncodedImage());               
                gpsData = imageToken.result.toString();
                metaResult.text = gpsData;
    protected function GetImageMetaDataFromExif(event:MouseEvent):void
                GetMetaDataFromExif();         
        ]]>
    </fx:Script>

    <s:HGroup>
        <s:Image id="test" width="130" height="140" source="@Embed(source='assets/p1000106.jpg')"/>

Hello everyone -
Since I last posted an interesting update happened. I tested my  Flex application again, it is calling a Jetty Server that returns a JSON object, in different BROWSERS.  I disabled HTTPS for now, and the crossdomain.xml policy file is wide open for testing (ie. allowing every request to return data). So the app accessing the data using HTTP only. Browsers  -  IE, Opera, Firefox and Chrome. Each browser contained the SAME application, revision of the Flash Player (10.3.183.10 debugger for firefox, chrome, opera, safari PC; 11.0.1.129 consumer version in IE9,) take a look at the screen shot (safari not shown although the result was the same as IE and chrome)
Note that Opera and Firefox returned successful values (i.e. successful JSON objects) using the same code generated from the Data Services Wizard. Chrome, IE and, Safari failed with an Internal error. So I am left wondering - WHY? Is it something with the Flash Player? the Browsers?  the Flex SDK? Any thoughts are appreciated. Again, the code is found in the original thread above.
