Java JDK Extension Attribute

javaJDKextAtty.txt

###Test Code###
### Intention is to figure out what JDK the user has installed.
### our current Ext atty reports the JRE, we need to know they have the JDK 
## thanks to elliotjordon
## -00 is just a number to say that JDK is not installed.  makes for better smartgroup searches

if JDKver=$(ls "/Library/Java/JavaVirtualMachines" | awk -F "_|.jdk" '/.jdk/{print $2}' | tail -1)
  then
  echo "<result>$JDKver</result>"
#      else
#       echo "<result>-00</result>"
fi

Another approach is to to run:
/usr/libexec/java_home
That should give me will give the current jdk path, which I can check for the right output.
