Capture device invisible by an applet

Question

Hello,
I wrote an application wich use a webcam, it worked fine.
I tried to make an applet using some part of code but there is a problem with the webcam and the audio.
When i use this code inside an application, it is ok. But when i execute this code inside an applet, deviceList2.size() was always equal to 0
public boolean initWebCam(){
          VideoFormat vformat =  new VideoFormat(VideoFormat.RGB);
          Vector deviceList = CaptureDeviceManager.getDeviceList( vformat );
          if(deviceList.size()==0){
               vformat = new VideoFormat(VideoFormat.YUV);
               deviceList = CaptureDeviceManager.getDeviceList( vformat );
          if(deviceList.size()==0){
               System.out.println("Attention... Aucune Webcam decouverte.");
               return false;
...JMF registry editor, inside the users settting : "Allow File Writing for applet", "Allow Capture for Applets" and "Allow Caching" is checked. Capture devices was display on the Capture Devices tab.
Does anyone know what is the problem or where to look for to see what is the problem ?
Thanks
Nicolas

Hi Nick
I recently use JMF and have exactly the same problem with you. When I test my applet in the development environment, i.e run the applet in applet viewer of JDeveloper IDE, the applet works just fine. However, when I deployed my application to webserver (Weblogic), the applet find 0 devices.
As I browse the webpage from the same machine with the Server, which means JMF is installed properly. And I checked JMFregistry, the Allow Capturing from Applet is also checked.
Have you find the solution yet?
Thank you very much
