Installing JDK 7 on Mac OS X
To get JDK 7 up,
- 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:
bone@zen:/System/Library/Frameworks/JavaVM.framework/Versions$ sudo rm CurrentJDK
bone@zen:/System/Library/Frameworks/JavaVM.framework/Versions$ sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_09.jdk/Contents/ CurrentJDK
Then, you should be good:
bone@zen:/System/Library/Frameworks/JavaVM.framework/Versions$ java -version
java version «1.7.0_09»
Java(TM) SE Runtime Environment (build 1.7.0_09-b05)
Java HotSpot(TM) 64-Bit Server VM (build 23.5-b02, mixed mode)
