Java Desktop development (Webcam)

I worked on an application that consist of 2 webcams. I'm having an issue where the webcams on this project are auto-balancing the light so that we don't get a good, bright photo of the item being photographed. Is there a way to manually "fix" the specs of the webcam from within the app? (Not to build in any adjustment mechanism that can be used by app users, but to set parameters, similar to the way the resolution gets set when the cams are initialized.)
