If you read the comments your IDE is giving you (if you are using one), or check the JavaDoc, you'll see that you have to specify buffers to hold all of your data.

The two types of buffers that you will use for that program are:

FloatBuffer

and

IntBuffer

Here is a sample of the surgery I had to perform to get the code working correctly:

        // Buffers hold sound data.
        static int[] buffer = new int[1];
        static IntBuffer soundBuffer = IntBuffer.wrap(buffer,0,1);
       
        // Sources are points emitting sound.
        static int[] source = new int[1];
        static IntBuffer sourceBuffer = IntBuffer.wrap(source,0,1);
       
        // Position of the source sound.
        static float[] positionValue = { 0.0f, 0.0f, 0.0f };
        static FloatBuffer sourcePos = FloatBuffer.wrap(positionValue,0,3);
       
        // Velocity of the source sound.
        static float[] velocityValue = { 0.0f, 0.0f, 0.0f };
        static FloatBuffer sourceVel = FloatBuffer.wrap(velocityValue,0,3);
       
        // Position of the listener.
        static float[] listenerPos = { 0.0f, 0.0f, 0.0f };
        static FloatBuffer listenerPosBuffer = FloatBuffer.wrap(listenerPos,0,3);
       
        // Velocity of the listener.
        static float[] listenerVel = { 0.0f, 0.0f, 0.0f };
        static FloatBuffer listenerVelBuffer = FloatBuffer.wrap(listenerVel,0,3);
       
        // Orientation of the listener. (First 3 elements are "at", second 3 are "up")
        static float[] listenerOri = { 0.0f, 0.0f, -1.0f, 0.0f, 1.0f, 0.0f };
        static FloatBuffer listenerOriBuffer = FloatBuffer.wrap(listenerOri,0,6);

Once you change the rest of the code so that the Float/Int Buffers are used where they're needed, the code should work fine. Let me know if you need any more help. (Code tested and works on Windows 7 using latest JDK update and Eclipse Juno)
