Capturing webcam inages: java.securty.AccessControllerException

[Michiel Bakker]

Hi guys,

I'm trying to capture images from a webcam in an ejb with a jsp as the
client. I'm using j2eesdk1.3.1 from Sun. When I call my image capture
function on the jsp I get the following error:

java.security.AccessControlException: access denied
(java.lang.RuntimePermission modifyThreadGroup)
java.io.IOException: Capture device in use

The device is not in use, I checked that. It seems that it has something to
do with securty restrictions. I'm not familiar with java.security and I' not
very experienced with ejb's. I was wondering if someone knows if this is a
security problem in the ejb. I tried the same code in a servlet and in the
servlet it works fine.
Any suggestions?

Thanks.

Michiel.
