CaptureDeviceManager.getDeviceList(null); Returns no devices!

Question

Hello,
Just installed JMF on Fedora Core 5. All works okay, jmfinit and jmfregistry can find my capture devices and list them also. Jmstudio also works fine when issuing the following command: java -Dawt.toolkit=sun.awt.motif.MToolkit JMStudio
However when i try to get my capture device(Bt484,bttv) from code i won't work.
Vector devices = CaptureDeviceManager.getDeviceList(null);
returns an empty list.
and
CaptureDeviceInfo di = (CaptureDeviceInfo) devices.elementAt(0);
of course returns an: java.lang.ArrayIndexOutOfBoundsException: 0 >= 0
There is no way i can approach my devices.....My classpath, jmf_home and permisssions are set right.
Anyone has an solution?
Thanks, and with kind regards,
Olly

private static void getList() {
          // TODO Auto-generated method stub
          Vector devices =
               (Vector) CaptureDeviceManager.getDeviceList(null).clone();
          Enumeration enum = devices.elements();
          while (enum.hasMoreElements()) {
               CaptureDeviceInfo cdi = (CaptureDeviceInfo) enum.nextElement();
               String name = cdi.getName();
               Format[] fmts = cdi.getFormats();
               System.out.println(name);
               for (int i = 0; i < fmts.length; i++) {
                    //System.out.println(fmts);
               if (name.startsWith("vfw:")){
               System.out.println(fmts[i]);
                    //CaptureDeviceManager.removeDevice(cdi);
