How to read a jp2 image into BufferedImage in java

Question

I want to read a jp2 image into BufferedImage in java. I installed the Java Advanced Imaging JAI. This is my code:

RenderedOp img = JAI.create("FileLoad",  "/home/dhoha/Downloads/BreastCancer.jp2");
  BufferedImage image =  img.getAsBufferedImage();

However, I get the following error:

Exception in thread "main" java.lang.RuntimeException: - Unable to render RenderedOp for this operation.
    at javax.media.jai.RenderedOp.createInstance(RenderedOp.java:827)
    at javax.media.jai.RenderedOp.createRendering(RenderedOp.java:867)
    at javax.media.jai.RenderedOp.getColorModel(RenderedOp.java:2242)
    at javax.media.jai.PlanarImage.getAsBufferedImage(PlanarImage.java:2498)
    at javax.media.jai.PlanarImage.getAsBufferedImage(PlanarImage.java:2546)
    at testJai.test.main(test.java:19)

I cannot understand why the JAI library is not able to read the jp2 images although this operation is feasible with the bmp images..

Any hint please???

Which version of JAI you have? Read this http://stackoverflow.com/a/13167748/1737819 — Developer Marius Žilėnas, Jan 06 '15 at 10:37
Yes I have intalled the older version of JAI 1.1 because the JAI 1.3 does not support the jpeg 2000 images... and currently I'm facing this problem. Any hints? — didowa, Jan 06 '15 at 10:44
Do import javax.imageio.ImageIO; import java.util.Arrays; public class ImageWriter { public static void main(String[] args) { System.out.println(Arrays.deepToString(ImageIO.getReaderFormatNames())); System.out.println(Arrays.deepToString(ImageIO.getReaderFileSuffixes())); System.out.println(Arrays.deepToString(ImageIO.getReaderMIMETypes())); } } does it list jp2 as a filetype? — Developer Marius Žilėnas, Jan 06 '15 at 11:53

Use the following:

import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;


InputStream ism=new FileInputStream("/home/dhoha/Downloads/BreastCancer.jp2");
BufferedImage  buffImg  = ImageIO.read(ism);
