I try to compile OpenCV on Ubuntu 12.10 I followed the steps in the guide: http://docs.opencv.org/2.4.4-beta/doc/tutorials/introduction/desktop_java/java_dev_intro.html

jdk-7-oracle installed but:

-- Could NOT find JNI (missing: JAVA_AWT_LIBRARY JAVA_JVM_LIBRARY JAVA_INCLUDE_PATH JAVA_INCLUDE_PATH2 JAVA_AWT_INCLUDE_PATH)

....

-- OpenCV modules:
-- To be built: core imgproc flann highgui features2d calib3d ml video objdetect contrib nonfree photo legacy gpu python stitching ts videostab

I have java-7-oracle installed on my ubuntu box and had the same problem. So I ran:

export JAVA_HOME=/usr/lib/jvm/java-7-oracle/

then I ran the cmake command again. And it appears to get further. I am still running into issues while making, but they me be unrelated.

Are you following the guide here?

I didn't have this problem when I was building, but I did install ant via apt-get before attempting to build.

apt-get install ant

Maybe this will help someone.

I had exactly the same problem (in my case using Debian Testing) and it was resolved by uninstalling all the open versions of Java and installing the proprietary one from oracle.
