cannot make opencv 2.4 with java support

edit

Hi

I'm trying to install opencv 2.4.5 with java support on my ubuntu 10.04 but without success.

What I did:

git clone https://github.com/Itseez/opencv.git

• cd opencv
• git checkout 2.4
• mkdir ./build
• cd ./build
• cmake -DWITH_TBB=OFF -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=/usr/local ..

What I get on cmake running:

Unavailable: androidcamera java ocl

Java:

  ant:                         /opt/java/apache-ant-1.9.1/bin/ant(ver 1.9.1)
  JNI:                         /opt/java/jdk-1.7/include /opt/java/jdk-1.7/include/linux /opt/java/jdk-1.7/include
 Java tests:                  NO

My question:

• why opencv tell me that java module is Unavailable?
