Your question doesn't make sense. Your code already compares the value of $JAVA_HOME to the string /pathhere; how this is or isn't "what's in there" is not quite clear.

Depending on your shell, you might need to add spaces inside the [[ ... ]] delimiters in order for the syntax to validate. Is that your problem?

Speculatively, if you want to check if a colon-delimited path contains /pathhere anywhere in it, and if not, add it, try this:

Code:
case :$JAVA_HOME: in *:/pathhere:*) ;; *) JAVA_HOME=/pathhere:"$JAVA_HOME";; esac

airport-modem

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

NAME

       airport-modem  - Modem monitoring and hangup utility for the original Apple AirPort Base Station ("Graphite"), the Lucent RG-1000 base sta-
       tion and the Apple Airport Extreme base station

SYNOPSIS

       airport-modem

DESCRIPTION

       airport-modem allows you to monitor the state of the internal modem of your base station and to start/stop the modem connection.

       On the AirPort Extreme base station, the modem utility can also display the approximate duration of the modem connection.

OPTIONS

       airport-modem accepts no command-line options. airport-modem is a wrapper script around the AirportBaseStationHangup.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.
