There is a simpler example here:
https://github.com/bytedeco/javacpp-presets/tree/master/flandmark
Let us know if you run into any problems with that one, thanks!

I see !
But Don't you agree that I need an file .dll to solve this exception ?

This Exception ocurred when I tried to load the file model.dat in this simple line:
org.bytedeco.javacpp.flandmark.FLANDMARK_Model model =
org.bytedeco.javacpp.flandmark.flandmark_init.flandmark_init("C:/flandmark/data/model.dat");
I'm using the same library like your pom.xml:
...
org.bytedeco.javacpp-presets
flandmark
1.07-0.9
org.bytedeco.javacpp-presets
opencv
2.4.9-0.9
org.bytedeco
javacpp
0.9
org.bytedeco
javacv
0.9
org.bytedeco
opencv-windows-x86.jar
2.4.9
...
I don't know what I can to do :'(

I follow the instructions, and it works just fine. To help you, I would need to reproduce the problem here on my machine. Please provide more details about what you are doing exactly.
from javacv-examples.
Ok. Thanks so much for your attention!
Firstly I did the download from http://cmp.felk.cvut.cz/~uricamic/flandmark/
I got the flandmark_v107.zip (latest zip from GitHub)
- Descompressed at C:/flandmark
- I already use opencv 2.4.9 and 2.4.8 ( I usually I use the 2.4.9)
I Noticed that when I extracted the flandmark, The structure of folders is:
- data
- examples
- learning
- libflandmark
- matlab_toolbox
- CMakeLists.txt
- AUTHORS
- INSTALL
- LICENSE
- README
Project JAVA
My libraries accorded as pom.xml :
M2_REPO/org/bytedeco/javacpp-presets/flandmark/1.07-0.9/flandmark-1.07-0.9.jar * not has .dll into this .jar, just has JNI class
M2_REPO/org/bytedeco/javacpp-presets/opencv/2.4.9-0.9/opencv-2.4.9-0.9.jar
M2_REPO/org/bytedeco/javacpp/0.9/javacpp-0.9.jar
The Simple Class
I simple class is bellow is enough to see the exception
public class SimpleExample {
public static void main(String[] args) {
org.bytedeco.javacpp.flandmark.FLANDMARK_Model model =
org.bytedeco.javacpp.flandmark.flandmark_init("C:/flandmark/data/model.dat");
}
}
When executed the method main :

I suppose that We needs the .dll files from flandmarks,
because when I downloaded flandmark, and came only source code in *.cpp
I struggled in generating files .dll from flandmarks_v107, But unsuccessful.
from javacv-examples.
How do you execute the main()
method?
from javacv-examples.
I use simple command:
java SimpleExample.class
But I'm running by eclipse.
I know that I need to put the variable -Djava.library.path= ???
But My doubt is What the directory specific I need to put in this variable ?
I generated by Cmake-gui the c:/flandmark, And generated bellow is where build to binaries indicated by Cmake-gui, the results of generating is it:
C:\flandmark-bin
- CMakeCache.txt
- CMakeFiles
- examples
- libflandmark
- matlab_toolbox
C:\flandmark-bin\CMakeFiles- cmake.check_cache
- CMakeGNUtoMS_lib.bat
- CMakeOutput.log
- CMakeTmp
C:\flandmark-bin\CMakeFiles\3.0.1 - CMakeCCompiler.cmake
- CMakeCXXCompiler.cmake
- CMakeDetermineCompilerABI_C.bin
- CMakeDetermineCompilerABI_CXX.bin
- CMakeRCCompiler.cmake
- CMakeSystem.cmake
- CompilerIdC
- CompilerIdCXX

- a.exe
- CMakeCCompilerId.c
C:\flandmark-bin\CMakeFiles\3.0.1\CompilerIdCXX - a.exe
- CMakeCXXCompilerId.cpp
C:\flandmark-bin\CMakeFiles\CMakeTmp
C:\flandmark-bin\examples - CMakeFiles

- flandmarkConfig.cmake
C:\flandmark-bin\libflandmark\CMakeFiles
C:\flandmark-bin\matlab_toolbox
- mex
C:\flandmark-bin\matlab_toolbox\mex- CMakeFiles
Now, I dont know if I need to generate another compilation .dll files starting folders above, to After I can put something like variable java.library.path=C:/flandmark-bin/dlls ???
Could you clear my doubt, in detail ?
Thanks for your attention and patience!
I'm almost there !!!

Ok so instead of using Eclipse, use Maven as shown in the simple example here and it will work:
https://github.com/bytedeco/javacpp-presets/tree/master/flandmark
from javacv-examples.
Thanks so much for your help !
I caught the jar flandmark-1.07-0.9-windows-x86.jar to solved the problem about JNI
