I looked at my /etc/bashrc and it is calling /etc/profile.d/java.sh, which looks like this:
Im going to assume that by 'calling' you mean that the entry in bashrc looks like this:

Code:
/etc/profile.d/java.sh

If that is the case, then you need to source the java.sh rather than executing it:

Code:
. /etc/profile.d/java.sh

That's a leading dot then a space.

When you export a variable in a script, it is placed into the environment, but is 'visible' only to that script and any processes that the script invokes. Environment variables don't/cannot perk back up to the parent process. If you are indeed invoking java.sh this is what is happening.

By sourcing the file, you are executing the commands in java.sh as though they existed in the current file, .bashrc in this case. This has the effect of setting the environment variables for the current shell as you desire.

AIRPORT2-PORTINSPECTOR(1)				      General Commands Manual					 AIRPORT2-PORTINSPECTOR(1)

NAME

       airport2-portinspector - Port maps inspector for the Apple AirPort Extreme Base Station ("Snow")

SYNOPSIS

       airport2-portinspector

DESCRIPTION

       airport2-portinspector allows you to inspect the port maps used by the hosts associated with your base station.

OPTIONS

       airport2-portinspector  accepts	no  command-line options. airport2-portinspector is a wrapper script around the PortInspector.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.
