Thanks. I've got it working now.
BTW, discovered that java_swt is not quite like java, specifically it
doesn't deal with the -jar command line flag.
This does not work:
java_swt -jar motd.jar
This does work:
java_swt -classpath motd.jar Motd

I had a problem with the tutorial because my Eclipse folder was renamed
"eclipse 3" and this was adding a space in the path that was interpreted
as a separator. It was the only problem that I had with the tutorial on
OS X.
