You can keep them on the server and use methods like getImage() and getAudioClip() to access them.The applet will download them when it needs them. Note, however, that an applet is only allowed to connect back to the server it was downloaded from.

I am accessing images and sound files using getImage and getAudioClip but every time i access it without a jar file it will make as many HTTP connections and i want to have only 1 HTTP connection to access a jar file only.
and also i want to reduce the size of my jar file. Plz suggest something for that

If you want to make one HTTP connection, then bundle everything in one .jar file, and make calls to Class.getResource() and Class.getResourceAsStream(). That way, all the files will already be downloaded.
As for JNLP, it's a way to do the Java WebStart thing. You have to package everything up the same way, and you wouldn't get any more benefits than by just packing it up in one jar file. It's useless for an applet.

I have done the same thing but everytime i am making a call to image it makes shows tha output in console window like this ::
jar:file:http://servername/my.jar!/redchips.png
why is that so ?
Thanx
