I have 1 DLL file need to call from Java, but when I run the Java app, I got the following error

Exception in thread "main" java.lang.UnsatisfiedLinkError: isBluetoothAvailable
at Test1.isBluetoothAvailable(Native Method)
at Test1.main(Test1.java:11)

=============

I didn't do much with JNI, but if I remember right, you call i.e.:

        static
        {
                try
                {
                        System.loadLibrary ("Xy");
                }
                catch (UnsatisfiedLinkError usle)
                {
                        usle.printStackTrace ();
                }
        }

On my platform, this will be libXy.so, which is searched, on your platform it should be Xy.dll or LibXy.dll - I guess the first is right, but the suffix is appended from the jvm.

The path for the library is specified by LD_LIBRARY_PATH on my system - perhaps C:/Windows/system32 is the easiest location to make it found.

Your code leads to "C:/ICubeXLib.dll.dll" beeing searched in C:/Windows/system32 or something like that.

Another posibility is that the dll doesn't contain that method with that exact signature.
