Applet with multiple class files
I'm new to java and I have made a sample applet with one class (in the default package) and have been able to load that in a browser. However I made a program that has one package (called applet) and under there are 2 class files. I have run the program in eclipse and it works fine, however when I copy both the .class files to my web server and do the embed tag with the code="MainFile.class" it won't work. Should it? or is there something special you must do when you have multiple class files.

seems u didn't get my point.
it is not possible to find a solution until we know the exact problem,i.e. the exact exception the jvm throws up.
you should try this:
put all your class files and the webpage with the applet code embed into it in a common directory, say, Desktop.
open the webpage using internet explorer.
on the ie menubar find the 'tools' menu.
you will see a "Sun Java Console" menu item there, if ur browser is java enabled.
open the console and look for the exact exception the JVM throws up.
