Description

The scripts under bin should be able to run without requiring the users to set DERBY_HOME explicitly. The script derby_common.sh, which is sourced by all the scripts under bin, contains code to detect DERBY_HOME based on the value of $0, but since the scripts need to know DERBY_HOME in order to source derby_common.sh, they still fail when DERBY_HOME is not set.

When I removed this part of bin/ij

-------

if [ -z "$DERBY_HOME" ] ; then
echo "Error: DERBY_HOME is not set. Please set the DERBY_HOME environment variable"
echo "to the location of your Derby installation."
exit 1
fi

. $DERBY_HOME/bin/derby_common.sh

-------

and in-lined the code in derby_common.sh in its place, I was able to run ij successfully by typing the command './bin/ij' without setting DERBY_HOME first.
