Currently i'm developing web app and i decided to use openCV library to use neural network. When i run my test controller which look like this:

@RequestMapping(value = "/test/neural/network", method = RequestMethod.GET)
public void test() {
    Mat output = new Mat(1, 20, CvType.CV_32SC1);

I had following error: Caused by: java.lang.NoClassDefFoundError: org/opencv/core/CvType

I'm using eclipse and configure environment step by step following the opencv tutorial. Moreover when i used the same code in console application, everything works fine. Probably i missing something, but i don't know what?
