but the problem is when i am unable to find the length of the video without actually playing using the Player class.i have tried the code given below

URL url = this.getClass().getResource( resourceName );
Player p = Manager.createPlayer( url );
p.start();
int state = p.getState();
while( state != Controller.Started )
{
try
{
Thread.sleep( 100 );
state = p.getState();
}
catch( Exception e )
{
e.printStackTrace();
}
}
Time duration = p.getDuration();

is it not possible to find the length of the video without actually playing it????please help me regarding this

I'm not familiar with JMF but the Interweb suggests you should be able to do it:
jmf player getduration - Google Search
and there might even be
