Problem with reading image file in Firefox

[AkbarAzizi]

Hi,

Is there anybody who knows why my following java/Groovy code does not work in Firefox?

The function ImageIO.createI mageInputStream returns NULL in Firefox.

The code works fine in Windows Explorer.

--------------------------------------------------------
def getImageFormat( CommonsMultipar tFile imageFile) {

String imageFormat
def file = new File(imageFile. fileItem.name)
ImageInputStrea m imageStream = ImageIO.createI mageInputStream (file);
if (imageStream != null) {
Iterator<ImageR eader> readers = ImageIO.getImag eReaders(imageS tream);

if(readers.hasN ext()) {
ImageReader reader = readers.next()
imageFormat = reader.getForma tName()
}

imageStream.clo se();
}

return imageFormat
}
