Flash player

hi everybody, my problem is simple but in the same time I don’t find some methods in vaadin to get it.
Question : How to detect if flash player is installed with vaadin version 6+ (not 7)? I found this thread :https://vaadin.com/forum#!/thread/152841 but without concrete solution :(, I need certain with vaadin (no js, no adobe kit)

Hi, I use 6.8.13 and have the same unexpected problem…
Has somebody resolve this problem with vaadin?
Can I see someware code example?
Thank you.
