Video Conferencing controls for development in java

Hello.

I am currently working on a video conferencing system. Does anyone know of any websites where I could get video conferencing controls that could be used for development in java?
I am looking basically for free controls or those that could be used for trial purposes.

Please reply as soon as possible. Thanks
