Hello
I'm retrieving a JPEG from the server side to display it in an mx:Image. The
image raw bytes are served by a plain Java Servlet. The content type is
correct. If I call the servlet from a common browser it all works fine. The
image is 400KB big.
PROBLEM: when I call the servlet from Flex 3, it looks like the lastResult
contains only the first bytes of the image, not all.
Briefly:
HTTPService declaration:
<mx:HTTPService id="arkServlet" url="/DocServlet"
useProxy="false" fault="fault(event)"
result="showImage()">
<mx:request>
<idDoc>101</idDoc>
</mx:request>
</mx:HTTPService>
The AS method that fires the http call:
public function downloadImage():void {
arkServlet.send() ;
}
The result callback:
private function showImage():void {
var imgBytes:ByteArray = new ByteArray() ;
imgBytes.writeObject(arkServlet.lastResult) ;
var imgLoader:FlexLoader = new FlexLoader() ;
imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,completeEventHandler);
imgLoader.loadBytes(imgBytes) ;
}
I am not posting the completeEventHandler() callback because it never gets
to execute it: it fails at imgLoader.loadBytes(imgBytes) giving the
following error (italian localized message):
Error #2044: IOErrorEvent non gestito:. text=Error #2124: Il file caricato รจ
di un tipo sconosciuto.
which translates more or less as
Error #2044: IOErrorEvent not managed: . text=Error #2124: loaded file is of
unknown type
Inspecting via debugger, it looks like the lastResult contains just a small
part of the 400KB.
Do I have to read the bytes explicitly in a loop in AS code ? Or is it just
my code that's wrong ?
Any help will be valuable, even debugging hints.
Thanks
Pier
