For me I had took care of following things -

1. Make sure fxml file is placed where your main class resides. And then load it using this - (In my case, TechJFX.fxml is the file)

   FXMLLoader loader = new FXMLLoader(getClass().getResource("TechJFX.fxml"));
   

2. Add opencv-*.jar to your project folder (In my case opencv-300.jar)

3. Add the jar to the build path using

Right click on the project folder -> Build Path -> Configure Build Path -> Libraries Tab -> Add External JARS and locate the jar

Also, under Order and Export -> Tick opencv-300.jar and JRE System Library(if not already ticked)

4. Copy opencv_java*.dll (In my case opencv_java300.dll) to the same location where you jar is in the project folder.

5. Add the following method to your main class

    static{ 
           System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
      }
   

6. Done.

Hope this helps someone facing similar issue.
