Set Java CLASSPATH for a set of library Jars using BASH

setclasspath.sh

#!/bin/sh

# use this for any package (such as ClearParser) which requires setting the
# classpath to a particular set of jar files

if [ -z $BASH_SOURCE ] ; then
        echo "Script must be sourced (using '.' or 'source') and run under bash >= 3.0"
        exit 1
fi
script_path="${BASH_SOURCE%/*}"
script_path_abs="$(cd $script_path ; pwd)"
jar_path="$script_path_abs/lib"

for jarfile in "$jar_path"/*.jar ; do
        if [ -z "$CLASSPATH" ] ; then
                CLASSPATH="$jarfile"
        else   
                CLASSPATH="$jarfile:$CLASSPATH"
        fi
done
echo "ClearParser base: $script_path_abs; CLASSPATH is now $CLASSPATH"
export CLASSPATH

If this bash script is saved alongside the 'lib' directory containing the jar files, it should just work, no matter where you source it from.
