Hi.
I have one question about Java on Mac OSX.
After spending some hours at : http://developer.apple.com/java/
And got some questions :
1. Why Apple's version of Java SDK is smaller than Linux and Windows version ?
No demo dir for example ?
Is Apple implementation of Java SDK is identical to Sun implementaion (No difference at all in functionality) ?
2. There is dir called : /System/Library/Frameworks/JavaVM.framework/
This dir contatins 3 or 4 versions of Java SDK, How to specify Java SDK 5 as my default SDK ?
3. There is also a dir called : /Library/Java/Extensions/
In this dir, we put Java jars.
It seems to me that Apple has changed the structure of Java SDK, is it true ?
4. I read about Application bundle in Mac OSX.
It seems to me that it allow us to create executable jar files (like exe on Windows), right ?
Well, it seems great if true.
5. Any good online tutorials about how to install Java SDK on Mac OSX ?
I'm really sorry guys for my questions about Mac OS X, but I'm trying to collect as possible information as I can.
(Please note that I'm talking about SDK not JRE)
Thanks.

This is the problem I had after installing Java 5.0. A resolution is posted here...

Note that in the 6th bullet point of these instructions, you could specify any of the version folders for the "CurrentJDK."


4. I read about Application bundle in Mac OSX. It seems to me that it allow us to create executable jar files (like exe on Windows), right?

I don't know much about this (yet), but the following is an interesting overview...
http://www.developer.com/java/other/article.php/1559241


5. Any good online tutorials about how to install Java SDK on Mac OSX?

Installation is easy. Just follow the steps here...
http://docs.info.apple.com/article.html?artnum=301073

The only trick seems to be in getting the "CurrentJDK" to alias the desired version, as described above in the answer to question 2.

You can make executable jar files on any platform - Mac OS X included.

Working with Manifest Files: The Basics

After making the executable jar you just double click on it (or as described in the tutorial 'java -jar <filename.jar>') and it should start the program.
