How to Get Emacs and Java for your Mac
 
Java for Classic Mac OS is located at http://developer.apple.com/java/download.html. Download MRJ 2.2. (MRJ 2.2.5 is an upgrade based on MRJ 2.2, so you must download MRJ 2.2 first.)
 
You can get Emacs 17.1 for Mac at ftp://ftp.cs.cornell.edu/pub/parmet. Or try Emacs 21.1 at http://mac-emacs.sourceforge.net/. Emacs 21 for Mac OS X is at http://members.shaw.ca/akochoi-emacs/.
 
Since classic Mac is not command line oriented, you have to go outside of emacs to compile and run your java program. This may be different in Mac OS X. I just haven't explored it yet.
 
To compile the java code, use "Javac". The simplest way is to drag your "*.java" file on top of the "javac" icon or alias. This resolves the path issue.
 
To run your application, use "JBindery". Again, the simplest way is to drag your "*.class" file (created by "javac") on top of the "JBindery" icon or alias.
 
To run your java applet, use "Apple Applet Runner". Here you use your "*.html" file which calls your java applet.
