JRE 1.5 to 1.6 Issue on Macbook Pro

I'm running Mac OS X 10.5.8 and have been trying over the past couple of hours to upgrade to Java 6. In doing this, I hope to change my Eclipse JRE to 1.6 so I can properly sync with my group's repo.

So far, no dice. I've downloaded every update I could find on Apple's website, and checked Java Preferences over and over. Not only is Java 6 not even there, the window that pops up looks nothing like the one detailed on Apple's website or any of the "upgrade to 1.6" tutorials I've found online.

I am now at a bottleneck: is this an Eclipse problem? I don't think so, since my OS X seems to be pooping itself, but I'm fairly sure there are literally no more updates for me to even try and install. Argh.

The newest way to configure runtimes, or JREs, is using Applications/Utilities/Java Preferences.app. The order defined here controls which version is used by browsers.

The command line utility /usr/libexec/java_home will show the current default version. Well-behaved scripts should be using the result of this command over the JAVA_HOME environment variable.

If you did an upgrade you also might have to manually change your JDK pointer.

cd /System/Library/Frameworks/JavaVM.framework/Versions
sudo rm -fr CurrentJDK
sudo ln -s 1.6 CurrentJDK

If if you try all this and you still only have a 1.5 install, remember that 1.6 is only supported on hardware that is Intel and x64 compatible. This affects some of the first MacBooks that included an Intel chip.
