We don't need to know any JNI to get this running, but you should be using Maven. How did you launch Maven?

[suvenduchakra]

I used command line to launch maven being in the project directory
mvn compile exec:java -Dexec.args="C:\Users\inschakra\Desktop\images\thumb_IMG_4088_1024.jpg C:\Users\inschakra\Desktop\images\thumb_IMG_4089_1024.jpg"

[saudet]

Could you copy/paste the whole output to the console of that command? Thanks

C:\Users\inschakra\Desktop\opencv-test>mvn compile exec:java -Dexec.args="C:\Users\inschakra\Desktop\images\thumb_IMG_4088_1024.jpg C:\Users\inschakra\Desktop\images\thumb_IMG_4089_1024.jpg"

I remember now, there's some dependencies missing: bytedeco/javacv#336 (comment)
Add these three lines to the beginning of the main() method.

hello guys
i am trying to write an opencv mat object into xml file to preserve it for later use but i got the following error. i don't know is there any problem with my code or something else.
any type of help would be appreciated..
Exception in thread "main" java.lang.UnsatisfiedLinkError: no jniopencv_core in java.library.path

this is my java code
opencv_core.FileStorage mfs= new opencv_core.FileStorage(String.valueOf(mymagnitude), opencv_core.FileStorage.WRITE);
mfs.open("test.xml", opencv_core.FileStorage.WRITE);
mfs.release();
"mymagnitude" is the mat object which i am trying to write to a file
