I'm currently using

Image img = Toolkit.getDefaultToolkit().getImage("./data/icon.png");

And it works great, but in this case I must place this image file next to jar for it to display...
and it isnt the best way to do it...

I have read everything I can find in google about reading image from inside a jar but nothing seems to work :(

Is there any reliable way to do it?

You can use,

Image img = getImage(getDocumentBase(), "book.gif");

It doesnt work...

The method getDocumentBase() is undefined for the type Application	Application.java	/Attempt3/src/simple/game/engine	line 23	Java Problem

I do something like this:

image = ImageIO.read(ClassLoader.getSystemResourceAsStream(imagePath+"imageName.gif"));

Well... for me it doesn't work too :(

Image icon = ImageIO.read(Application.getSystemResourceAsStream("./data/icon.png"));

error:

Why Application? you must call ClassLoader.getSystemResourceAsStream, not Application.getSystemResourceAsStream!

That doesnt work either way, that's why i tried to change it.
If it's

Image sprites = ImageIO.read(ClassLoader.getSystemResourceAsStream("data/sprites.png"));

error:

This actually makes it sound as if the images is outside the .jar file in the same directory. But it isn't, right?
Next, could you tell us if the class you're trying to open the image file from is in a package? (if so, provide the full name, please)
AND do you put the images in the root of the jar-file, or deeper( like in a "/Images" directory)?

Of course you're getting that.
Replace that line with this:

try {

    Image sprites = ImageIO.read(ClassLoader.getSystemResourceAsStream("data/sprites.png"));

} catch(IOException e) {

    System.out.println(e);

}
