"Unsatisfied Link" exception when trying to use JNI

I have the following Java class:

package no.gaiasoft.fotoboks;
public class Capture {
  // native method declaration
  native byte[] grabImage();
  // Load the library
  static {
    System.loadLibrary("canoncapture");
  }

  public static void main( String args[]) {
    byte buf[];
    Capture img = new Capture();
    buf = img.grabImage();
    String s = new String(buf);
    System.out.println(s);
  }
}

This I run thru javah to get this header file:

/* DO NOT EDIT THIS FILE - it is machine generated */
#include <jni.h>
/* Header for class no_gaiasoft_fotoboks_Capture */

#ifndef _Included_no_gaiasoft_fotoboks_Capture
#define _Included_no_gaiasoft_fotoboks_Capture
#ifdef __cplusplus
extern "C" {
#endif
/*
 * Class: no_gaiasoft_fotoboks_Capture
 * Method: grabImage
 * Signature: ()[B
 */
JNIEXPORT jbyteArray JNICALL Java_no_gaiasoft_fotoboks_Capture_grabImage
  (JNIEnv *, jobject);

#ifdef __cplusplus
}
#endif
#endif

I implement "canoncapture.dll" in visual studio like this:
#include "stdafx.h"
#include "jni.h"

JNIEXPORT jbyteArray JNICALL Java_no_gaiasoft_fotoboks_Capture_grabImage
(JNIEnv * env, jobject jobj) {

 jbyteArray jb;

 jb = env->NewByteArray(15);
 env->SetByteArrayRegion(jb,0,14, (jbyte *)'A');
 return (jb);
}

I put "canoncapture.dll" in java.library.path, and run Capture.
this gives me the error:

Exception in thread "main" java.lang.UnsatisfiedLinkError: grabImage
at no.gaiasoft.fotoboks.Capture.grabImage(Native Method)
at no.gaiasoft.fotoboks.Capture.main(Capture.java:17)

Can anyone shed som light on what i might be doing wrong here?

TIA...

Listen to your brain - it has a lot of information.
