I have intalled the open CV(2.4.9) from this tutorial.
I have added on Windows sistem path this variable :

C:\Program Files\Java\opencv\build\x86\vc10\bin;
I have create the executable jar as in this tutorial.

Have you suggestions?Why the application work correctly on eclipse and not work in the executable jar?

Thanks for help.

From previous discussion, you mentioned this is your library: C:\Program Files\Java\opencv\build\java\opencv_java249.jar. Can you verify it's actually been included in the JAR that you packaged? — Ryan J, May 29 '14 at 20:50
My java.library.path is : C:\Program Files\Java\jre7\bin;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:/Program Files/Java/jre7/bin/client;C:/Program Files/Java/jre7/bin;C:\Program Files\Java\apache-tomcat-6.0.18\bin;C:\Program Files\Java\sdk\tools;C:\Program Files\Java\sdk\platform-tools;C:\Program Files\Java\jdk1.7.0_25\bin;;C:\Program Files\Java\eclipse — user3675796, May 29 '14 at 20:55

Sorry, I dont't have solutions.

I must pack my openCV.jar library into an executable java project .jar.

I had the same problem.

It happened because I had a mistake with the 'Native library location' configuration:

Goto Eclipse -> Window -> Preferences:

Goto Eclipse -> Window -> Preferences

Goto User Libraries:

enter image description here

Make sure that your native library location path is (change c:/opencv-2.4.9 to your own opencv folder):

C:/opencv-2.4.9/build/java/x64

and not:

C:/opencv-2.4.9/build/x64

(I missed the /java folder...)
