问题
At my school I am using Notepad++ to write an applet, and I need to package it in a jar so I can sign it. I am attempting to do this with a batch file like this:
CD C:\Users\name\Java\bin
javac className.java
jar cvfm className.jar Manifest.txt classFolder
java -jar className.jar
PAUSE
And then I get a main method not found exception. There is not much I can do in terms of debugging, or opening up my jar, because as I said before, it is at school and so much of the functionality is blocked. I can provide more details if needed, thanks.

Applets don't have a main method, so you cannot run it in the conventional way with the java command.
To run the applet, create an HTML file with the applet in it, and run appletviewer or view the page in a web browser.

You shouldn't run an applet that way. It's not an application to run via the java command, and usually doesn't have a main method (unless you're writing some dual-purpose program). Run it with HTML code. The applet tutorial will show you this, and surely you've read this already.
