Location of javaw on the Mac

Question

I have a shell script on the Mac which looks for javaw. i.e.:

#!/bin/sh
javaw -version 2> /dev/null
if [ $? == 0 ]; then
  javaw -jar some.jar
else
  echo "Java Runtime not installed or JRE executable not in PATH"
fi

but it gives this error when I run it:

Java Runtime not installed or JRE executable not in PATH

Clearly it can't find javaw. So, my question is - where is javaw on Mac OS X [Version 10.10.2 (14C109)]?

==== UPDATE

Java is installed. e.g:

$ java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

This may take a while to run, but should find it `sudo find -x / -name javaw 2> /dev/null` — Mark Setchell, Mar 05 '15 at 22:40
Neat, thanks - haven't seen the `-x` flag before. The results - given that I had Java installed I assumed `javaw` would also be installed. Using `find` it turns out it is not. — Snowcrash, Mar 06 '15 at 10:21
