Nullpointer exception package javapplication15; http://docs.opencv.org/doc/tutorials/introduction/desktop_java/java_dev_intro.html I tried this tutorial mentioned above and got the following error. I am pretty sure that the files are present in corresponding folders as mentioned in the Tutorial. I think this is a path issue and I tried things like giving the absolute path and other things that can be found online. Still not luck. I am suing NetBeans 8.0, OpenCV 2.4.9 and Windows 8 |
