Please, check the file paths to all the PNG files - i.e.
- image0.png
- image1.png
- image0.png (dont forget the last one)

Thanks for the quick answer, but i already checked that. To be sure about that,
i just deleted the images, now i get a different Error (Runtime Error - Array
should be CvMat or IplImage...), so this is not the Problem.
With the last one i guess you mean image0-1.png
I already figured out, that the cvCalcOpticalFlowPyrLK causes the problem.
Now i tried on another System, Vista 32bit, OpenCV 2.1, Netbeans 3.8: same
problem
I would say there is something wrong with the environment, but no idea what. I
have the latest Java Version, OpenCV 2.1, added the .jar (JNA and JavaCv) to my
Project. That shuold have been all.

I have almost the same configuration as you mentioned before:
OpenCV 2.1, Windows 7 Professional 64bit, Eclipse IDE (not importatnt), JRE
version 1.6.0_23
I think that the problem is in DLLs
You can try these DLLs:
http://spl.utko.feec.vutbr.cz/cs/component/content/article/21-zpracovani-medicin
skych-signalu/261-rapidminer-5-opencv-extension
Download the i686 version
http://spl.utko.feec.vutbr.cz/images/stories/rapidminer/rmx_opencv/opencv210_Win
_i686.zip
Run the JRE with this VM argument:
-Djna.library.path=c:\path\to\downloaded\DLLs

Sorry, i dont really know what i should download here.
The first link points to a homepage with a lot of dead links, do you mean i
should try something with rapidminer?
second link does not work either

Sorry for that and thank you for notifying me about that. The links on the site
should be now corrected.

Thanks, links work fine now!
I did what yous suggested, downloaded the new .dlls, and ran the code with the
VM argument (of course with my own path to the .dlls).
I'm sorry to say, that nothing changed, still the same Error. But i have some
new information which might help:
Sometimes the build is successful! I dit not change anything, but in maybe 1 of
20 builds i do not get an Error.(I really keep on klicking and re-executing the
program until it works). This happens both with your new .dlls and also with
the old .dlls
The whole thing is getting even more confusing now, I have no idea what cuold
cause such an undeterministic behaviour...
But thanks a lot for your effort, i really appreciate it

These lines are incorrect:
CvPoint2D32f[] cornersB = new CvPoint2D32f[MAX_CORNERS];
for (int i = 0; i < MAX_CORNERS; i++) {
cornersB[i] = new CvPoint2D32f();
}
Please refer to the README.txt to see how we need to allocate arrays..

thank you Samuel!
i replaced the array allocation with:
CvPoint2D32f[] cornersB = CvPoint2D32f.createArray(MAX_CORNERS);
now it works! I am very glad that my environment was set up corretly, was
beginning to doubt myself.
Still, i am very greatful for the examples
