great answer.  i wrote my previous email prior to receiving yours.  i 
think the location for JAVA_HOME is the problem eh?  what is JAVA_HOME?

[eric at mathPlayPen eric]$ export 
PATH="$PATH:/opt/j2sdk_nb/j2sdk1.4.2/jre/bin"
[eric at mathPlayPen eric]$ export JAVA_HOME=/opt/j2sdk_nb/j2sdk1.4.2/jre/lib
[eric at mathPlayPen eric]$ /usr/bin/jedit
/usr/bin/jedit: line 13: /opt/j2sdk_nb/j2sdk1.4.2/jre/lib/bin/java: No 
such file or directory
/usr/bin/jedit: line 13: exec: 
/opt/j2sdk_nb/j2sdk1.4.2/jre/lib/bin/java: cannot execute: No such file 
or directory
[eric at mathPlayPen eric]$

i don't understand the first problem because there IS a file called java 
in /opt/j2sdk_nb/j2sdk1.4.2/jre/lib/bin/  isn't that what it's looking for?

mmmnnn...

i'll search around some more and try out some shots in the dark prior to 
posting again.  thanks for any ideas, eric.
