I normally don’t mess with Java so this is likely a trivial point, I could very well be stating the most obvious of obvious things.
The documentation for Amazon’s EC2 Web Service actually had a well written explanation, but who reads? Scanning the setup instructions I saw:
- Java. — Check, I got that
- Java JRE version 1.5 — Check?
[smbrown@jrcash$] java -version - JAVA_HOME — Check?
[smbrown@jrcash$] which java - FAIL
JAVA_HOME is /Library/Java/Home it is the location where the sub folders bin/java/
What is my “JAVA_HOME“? it is “the full path of the directory that contains a sub-directory named bin which in turn contains the java“
To see your current JAVA_HOME:
[smbrown@jrcash$] echo $JAVA_HOME
To set a JAVA_HOME, insert this in your ~/.profile:
JAVA_HOME=/Library/Java/Home
export JAVA_HOME;
What is a better way to confirm your real Java version JAVA_HOME on OS X?
[smbrown@jrcash$] $JAVA_HOME/bin/java -version
Thanks for taking a look you can go back to Twittering now. =)
