Can anyone give idea about video streaming in web browser through java or jsp

I need to play video presentation in my web browser to show all members of the company.For I want to put my video file in web server and anyone can access that video just playing on their browser our web browser is firefox.



We don’t want to use any active X properties or any default media player in web browser . Our Platform is linux fedora core4, web server is tomcat 5 . We read the JMF java media Framework API, but I couldn’t understand how to use this in our server for linux. There is scripts for player in java
