If this is the first time you've seen an applet's code then it might look a little goofy, but it all works to help the applet run correctly. I should say here that this code will not work if you simply transcribe it to your page right from here. This code was created just for me. You see, when you sign up with Chat Planet, an applet is created just for you. After it's created, it's placed in a directory.
CODE tells the browser which file inside the directory to use.
In this case I am using an applet called eweb.chat.ChatApplet.class. You have to have this. Applets work inside their one little window. The height and width settings define the window. Some applets allow you to change the height and width.
