Amir,
Applets are client side code. To deploy an applet you place the applet’s class on a web server and use a html page with the applet tag to reference it. Unlike web apps, applets do not really have a “deployment” process. You just put them in one of the publicly accessible directories, and they’re available right away. Any jar files you have will go into the same directory that the HTML file containing the applet is in.
As soon as the client processes the page, the class is transferred to the client and runs there locally.
If you are looking to run an applet in a web application, then please check these links :

I suggest you cross post on Applet forums or look for tutorials on the web for better support.
