derby from the CLI

[Thufir]

I'm kinda sorta able to use derby ij:


root at dur:~/apache-james-3.0-beta4/var/store/derby# 
root at dur:~/apache-james-3.0-beta4/var/store/derby# echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games
root at dur:~/apache-james-3.0-beta4/var/store/derby# 
root at dur:~/apache-james-3.0-beta4/var/store/derby# echo $DERBY_INSTALL

root at dur:~/apache-james-3.0-beta4/var/store/derby# echo $CLASSPATH
/opt/db-derby-10.9.1.0-bin//lib/derby.jar:/opt/db-derby-10.9.1.0-bin//lib/
derbytools.jar:

root at dur:~/apache-james-3.0-beta4/var/store/derby# java 
org.apache.derby.tools.ij 
ij version 10.9
ij> quit;
root at dur:~/apache-james-3.0-beta4/var/store/derby# 


However, if I open another console, I get:



thufir at dur:~$ 
thufir at dur:~$  java org.apache.derby.tools.ij

surely I don't need to run this setNetworkClientCP script again, do I?
