[sdljava-users] SDLjava Error in sdljava.x.swig.SWIG_SDLVideoJNI.SDL_SEtVideoMode

[Toni P. <teh...@go...>]

I'm trying to run my project with the following code:
public class HelloSDL {

   static {
      System.loadLibrary("SDL");
      System.loadLibrary("SDLJava");
   }

   public static void main( String[] args ) {
         try {
            SDLSurface screen = SDLVideo.setVideoMode(640,480,0,1);
         } catch (SDLException e) {
            e.printStackTrace();
         }
   }
}

First, he couldn't load the library and dependent libraries, but it works
now ...
But If I run the code, an error occurs:
Exception in thread "main" java.lang.UnsatisfiedLinkError:
sdljava.x.swig.SWIG_SDLVideoJNI.SDL_SetVideoMode(IIIJ)J
    at sdljava.x.swig.SWIG_SDLVideoJNI.SDL_SetVideoMode(Native Method)
    at sdljava.x.swig.SWIG_SDLVideo.SDL_SetVideoMode(SWIG_SDLVideo.java:38)
    at sdljava.video.SDLVideo.setVideoMode(SDLVideo.java:332)
    at HelloSDL.main(HelloSDL.java:14)
Why is this?
Thanks for any help.
