if you are setting the JAVA_HOME in a script, You need to remove the # from the beginning of the line. It's commenting out whatever follows it on that line.

to see what a specific variable is defined as:
echo $VARIABLE

so in your case you would do:
echo $JAVA_HOME


if it comes out blank, it is not defined.

AIRPORT-LINKMON(1)					      General Commands Manual						AIRPORT-LINKMON(1)

NAME
airport-linkmon - Wireless link quality monitor for the original Apple AirPort Base Station ("Graphite") and the Lucent RG-1000 base sta- tion SYNOPSIS
airport-linkmon DESCRIPTION
airport-linkmon allows you to measure the signal strength and noise on the wireless links between your base station and its associated wireless hosts. OPTIONS
airport-linkmon accepts no command-line options. airport-linkmon is a wrapper script around the LinkMonitor.jar jar file located in /usr/share/java/airport-utils. You can set the JAVACMD environment variable to use a specific JVM instead of the one chosen by the wrapper script. Set the DEBUG environ- ment variable to 1 to get the debug output from the wrapper script. ENVIRONMENT VARIABLES
DEBUG Set this variable to 1 to get the debug output from the wrapper script. JAVACMD The full path to the Java Virtual Machine to use. By default, the wrapper uses JAVACMD; if it is not set, it looks for JAVA_BINDIR/java, then for JAVA_HOME/bin/java before looking for a java executable in the PATH. In the latter case, the JVM used can be configured using the Debian alternatives system (see update-alternatives(8)). JAVA_HOME The full path where your JDK/JRE is installed. JAVA_BINDIR The full path to the directory where the java executable is located. JAVA_ARGS Extra command-line arguments to be passed to the Java Virtual Machine. AUTHOR
airport-linkmon was written by Jon Sevy <jsevy@cs.drexel.edu>. This manual page was written by Julien BLACHE <jblache@debian.org>, for the Debian project (but may be used by others). May 20, 2006 AIRPORT-LINKMON(1)
