I am using JMyron to capture images from my webcam. I have a JFrame which displays the camera image and it works fine if I start the program after plugging my camera.

If I unplug my cam and start the program I get a warning message that says "There is no video capture device" and program crashes on this line:

1. jMyronObject.update();

I am getting the following error message:

21. Myron: myron_ezcam_run() failed
22. myron_ezcam_run() failed at cam->initCamera()
23. Java Result: 1

try-catch block does not catch the exception. How can I check if there is a camera so I can handle no camera case?
