Java Question

Where is Java Installed on Mac OS X?

I just downloaded Java 7u17 on Mac OS 10.7.5 from here and then successfully installed it. In order to do some JNI programming, I need to know where Java installed on my Mac.

I thought that inside the

/Library/Java/JavaVirtualMachines/
folder, there would be a folder called
1.7.0.jdk
or something, but then I found that the folder is empty. This was confirmed by running
ls /Library/Java/JavaVirtualMachines/
in the Terminal. I've tried searching for it to find out if it was installed somewhere else, but that doesn't seem to be turning anything up.

Could someone please tell me where Java is installed on my Mac?

Answer

Use /usr/libexec/java_home -v 1.7 command on a terminal shell to figure out where is your java 1.7 home directory
