+1 Q:

Should I use JAI?

I would like develop program with a lot of image processing. I would like to use Java, and JAI, but it seems to me, that Jai is old and no longer evolve? (http://java.sun.com/javase/technologies/desktop/media/jai/)

I wonder, is it better choice to use QT and c++?
Two main pros which I am looking for is: cross platform code and good learning opportunity.

+1 A:

If you're wanting to do image processing, then what JAI did 3 years ago will be sufficient for the mathematical base of what you want to do now. New image formats etc would probably not require new updates to JAI.

I just can't think of anything that you'd need to add once you've got the basic operations - it's the application on top that's going to get new features.

Now how you get your graphical ideas into an Image that you can then process... awt, swing, Java FX...

If you go to your system tray with the java icon, right-click and show java console, then you'll see that you're getting a `ClassNotFoundException` on `javax.media.jai.PlanarImage`. It would seem that you need to drop the jai.jar into your jre/lib/ext folder for it to work

Yep! Worked for me - just install JAI on your computer and away you go.

Thx, +1, so is there any way to compile WITH that classs? It probably called "static compiling"? If user have to install it by itself, he probably give up.

You just bundle the jai jars as you would any other in your application. The installer merely upgrades a client JRE in so that you only installed it once. This is better for applets, and was probably done pre-webstart as well. Speaking of web-start, you could also try https://jai-webstart.dev.java.net/examples.html, but I couldn't get those to download nicely on my connection...
