UnsatisfiedLinkError with JNI

Question

I have what I think is a strange problem, because last year this program worked, and this year it doesn't. Obviously something has changed, but I can't figure out what.
What I am doing here is using the JNI to call a Native Method to get some data from a A/D.
However, now when I try to call that method, I get the following error:
Caused by java.lang.UnsatisfiedLinkError; fileiotest.dllinterface.startget()UAlso, here is the code for the dllinterface file. It's simple and short, so I think I can paste the whole thing
package fileiotest;
* @author Owner
public class dllinterface {
    public native void startget(int channels);
    public native float[] getpoint(int channels);
    public native float[] gettimepoint(int channels);
    public native void stopget();
    private static dllinterface DI;
    private float newtempfloat[] = new float[9];
    static {
     System.loadLibrary("daqdll");//This is firstJNI.DLL
     DI = new dllinterface();
     /*if generated by borland
     System.loadLibrary("firstjni");//This is firstjni.dll
    public void start_daq(int channels)
     DI.startget(channels);
    public void stop_daq()
       DI.stopget();
    public float[] get_data_point(int channels)
      newtempfloat = DI.getpoint(channels);
      return newtempfloat;
    public float[] get_data_time_point(int channels)
      newtempfloat = DI.gettimepoint(channels);
      //System.out.println(newtempfloat[channels]);
      return newtempfloat;

Answer 1

You are loading the dll successfully.
So that means the dll changed.
