what is my $JAVA_HOME path

Question

Just launched an instance of EC2 and I tried doing:

$JAVA_HOME/bin/java -version

it gives me back:

 $JAVA_HOME/bin/java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.1) (amazon-44.1.9.1.21.amzn1-i386)
OpenJDK Client VM (build 19.0-b06, mixed mode)

so I can see that it is installed there. I opened up my bash profile however I don't see what my JAVA_HOME path is? How do I get this? THanks

Solution

echo $JAVA_HOME

or

env | grep JAVA
