How to post event to a dialog when a video capture device is connected in java

I am trying to post an Event or notification to a dialog or frame , when a video capture device is connected to a system.(Mac OS X). I am trying to do it with java . Any help would be far kind.

You might want to look into the Java Media Framework . Its CaptureDeviceManager class seems to offer the required facilities. I've shortly experimented with JMF and found it to be quite easy to get a stream from a webcam and output it to a Swing container. Took minimal effort.
