Ok, gotcha! You need to use Loader.loadBytes(b:byteArray) var loader:Loader = new Loader();
loader.loadBytes(yourByteArray);
Now, the bitmap *will* be available in the loaders content property, but do
not assume that just because you gave it a preloaded bytearray that it will be
*immediately* available. Or you will be sad and confused, as was I :)
No, the bitmap will only be available once the loader.contentLoaderInfo
complete event fires.
So, add an event listener for the complete event :
loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loaderCompleteHandler);
Then get the bitmap from the loader at that point in time :
private function loaderCompleteHandler(event:Event)
{
var loader:Loader = event.target as Loader;
var bmp:Bitmap = Bitmap(loader.content);
// do something with bmp here, such as displaying it.....
}
I'm not sure if the image component now will take a byteArray directly, there
was some talk of it a few months back so it may have got added to the flex 3
code.

Is your question
a) how to get the byteArray into flex?
b) how to display it once it is in flex?
c) both a and b ?

Subject: [flexcoders] How to download a BLOB from database.... using Java
Hi all....
I would like to know...how to download a BLOB (image, file...binary
data) from my Oralce database to my Flex application.
I think i already have my servlet created....the souce can be more
or less like the next one:
Session session = HibernateSessionFac tory.getSession( );
//Here i get my POJO (my movieImage object)
MovieImage myMovieImage = (MovieImage) session.load( MovieImage. class,
movieId);
//I got the binary data (in this case one image), into array of bytes
byte[] myCover = myMovieImage. getCover( );
ServletOutputStream servletOutputStream = res.getOutputStream ();
res.setContentType( "application/ image");
res.setContentLengt h(myCover. length);
servletOutputStream .write(myCover, 0, myCover.length) ;
servletOutputStream .flush();
servletOutputStream .close();
But my problem is how to show that image in my component... .
Can someone help me (with some source or with some steps or some
example) to get the solution?
Thansk in advance.
