Failed to start JMagick

I have a strange problem with the JMagick library. I am using Debian, so I installed libjmagick6-java and libjmagick6-jni and here are the steps I took:

• I copied jmagick-6.6.9.jar
  
  from /usr/share/java/
  
  to $JAVA_HOME/jre/lib/ext/
  
  .
• I have set /usr/lib/jni
  
  (where libJMagick.so
  
  ) as the local library location to:
  • JRE Systems Library (in eclipse)
  • jmagick-6.6.9.jar (in eclipse)

Also I tested JMagick in a simple Java project and there it works, but in a second project that works in Tomcat 6 it just doesn't work.

Here is my code that WORKS - so jmagick should be installed correctly:

public class Main {
    public static void main(String[] arg) {
        MagickImage image = null;
        ImageInfo imageInfo = null;

        try {
            imageInfo = new ImageInfo("/home/firzen/IMG_0120.JPG");
            image = new MagickImage(imageInfo);
            System.out.println(image.getDimension().width);
        } catch (MagickException e) {
                System.out.println(e);
        }
        image.destroyImages();
    }
}

      

        
        
        
      

    

And here is the code in the webapp that DOESN'T WORK :

public void init() {        
    ServletContext sc = getServletContext();
    cacheHandlers = (Map<String, CacheContext>) sc.getAttribute("handlers");
    Boolean applicationReady = (Boolean) sc.getAttribute("ready");
    isReady = cacheHandlers != null && Boolean.TRUE.equals(applicationReady);

    System.out.println("zde");
    MagickImage image = null;
    ImageInfo imageInfo = null;

    try {
        imageInfo = new ImageInfo("/home/firzen/IMG_0120.JPG");
        image = new MagickImage(imageInfo);
        System.out.println(image.getDimension().width);
    } catch (MagickException e) {
            System.out.println(e);
    }
    image.destroyImages();
}

      

        
        
        
      

    

Finally, this is the exception thrown by the above code:

Please tell us some ideas how to solve this problem. Thanks in advance!
