Where is my Java SDK 7u7 installed? I downloaded and installed Java 1.7 from this site.

When I run the Java Control Panel, I could check I have it correctly installed. 



However, when I checked the Java version from command line, the version that I use is Java 1.6.

java -version
java version "1.6.0_33"
Java(TM) SE Runtime Environment (build 1.6.0_33-b03-424-11M3720)
Java HotSpot(TM) 64-Bit Server VM (build 20.8-b03-424, mixed mode)


The system directory doesn't have the 1.7.



What's wrong with this?


Where is the Java 1.7 is installed?
How can I make the Java 1.7 as default Java?
I found Java 1.7 SDK in /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk, and all the binaries in /Library/Java/JavaVirtualMachines/jdk1.7.0_07.jdk/Contents/Home/bin. 



And by clicking the jdk file, I could arrange the order so that Java SE 7 is executed first.

java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)


And I could also bring up the app from /Applications/Utilities/Java Preferences.app



For eclipse, I could add one line in /Applications/eclipse/Eclipse.app/Contents/MacOS/eclipse.ini to teach eclipse what Java it will use : 

-vm
/System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/bin/java
