adobe flash player
poster don't bother urself, u won't get it on java but it's available on symbian platform (smart phone)
I dont think that the Adobe flash player lite will work for your k310i java phone as the software is a symbian application.Besides,it is a stand-alone application,so don't expect to be watching flash videos online on your mobile.
Adobe flash player lite
Adobe has its mobile version for the flash player.
