- I downloaded the JDK from Oracle. They have a nice dmg file, which makes it easy to install.
- After reading their installation instructions and running /usr/libexec/java_home (which I didn't even know about), it still wasn't defaulting to JDK 7.
Surgery required. So, I headed over to:
This is where the system jvm's are stored. You'll notice a symbolic link for CurrentJDK. It probably points to:
You're going to want to point that to the new JDK, which java_home tells us is located in:
So, the magic commands you need are:

This tutorial shows you how to install Java SE 7 Developer Preview on Mac OS X 10.7.2 Lion running on my MacBook Pro.
1. Download the Oracle JDK7 Mac OS X port dmg file from here. At the time of this writing, the version of the JDK7 is Oracle JDK7 build b223 released on December 23, 2011. The dmg file name is jdk-7-ea-macosx-b223.dmg
2. Create a JavaVirtualMachines folder under /Library/Java if it doesn’t exist.
In my case, the JavaVirtualMachines is already there so I don’t need to create it manually.
3. Open the jdk-7-ea-macosx-b223.dmg file by double-clicking on it. Then drag the JDK 1.7.0 Developer Preview icon in the left side to the JavaVirtualMachines icon folder in the right side.
4. Go to /Library/Java/JavaVirtualMachines directory using Finder application. Then double-click the ‘JDK 1.7.0 Developer Preview’ icon. This will open the Java Preferences window. Here you can change the preferred order of the installed Java platforms by dragging it up or down. Make sure the Java SE 7 is in the preferred order or you can simply deselect the Java SE 6 version.
5. Now issue the ‘java -version’ command in the terminal window to verify.
6. Done
