--------------------------------------------------------

PROBLEM
If I 
1. put my app in /usr/local/myapp
2. ln -s /usr/local/myapp/bin/myapp /usr/local/bin/myapp

Then the classpath is determined to be the jars found in /usr/local/repo/ which 
does not exist.

SOLUTION
The unix shell script should start with...
 PROGRAM=$(readlink $0)
 if [ $? -ne 0 ]; then
   PROGRAM=$0
 fi;
 BASEDIR=`dirname $PROGRAM`/..

And not...
BASEDIR=`dirname $0`/..
