I'm writing a midlet that at some point downloads an image from the web. The image is quite large and I'm wondering whether exists a library that can read and render progressive JPEG files. I've searched the net but I could not find an answer to that...
I wouldn't be too surprised to hear that it's pretty much standard these days.
Try it and see.
I think that the "Java In a Nutshell" book from O'Reilly has some examples. Not J2ME, but with luck it'll be pretty much the same.

Just to answer this question for future reference, it seems that progressive jpegs are not yet supported.I've found many jpeg decoders but none claimed that it could render a progressive jpeg. I have tested many ways of displaying a progressive jpg but the picture just appeared all at once.
In order to test it yourself you must find a progressive picture that is smaller than your display, cause if it is larger the browser only gets the first (less detailed) layer anyway.
