Best way to access web camera in Java

Question

I need to access web camera using Java  This is what I want to do   Access web cam  Now the user can see web cam working because his face is visible on screen  have heard some libs are there which doesn t show the video output of webcam   when user click save button  take a snapshot and save it   I have tried number of ways to do this  from a long time    JMF - Now it is dead FMJ - Now it is dead too VLCJ - too much because I am not creating a music video player and it expect VLC to be installed Xuggler - too much and hard work JMyron - didn t work JavaFX - I thought it could do it  but seems like it can t   I am even satisfied if the library is just ONLY doing the above mentioned  because that s enough for me  But I expect it to be simple too  Really great if it is not using DLLs  because it is not platform independent if it does  Really appreciate if it can DETECT the camera  without manually passing the camera name and other info as have do in VLCJ  because there might be thousands of camera brands  so I can t create a list of thousand elements in it   And  I am creating a desktop application  not web app   If you know a library like this  please be kind enough to let me know  Other libraries  which might not suit to all of my requirements  but suits to the basic requirement  also welcome  Please help
