[jdom-interest] NoSuchMethodError while running samples

[Nick Fankhauser]

Amy gets the prize for figuring out the ultimate cause of all three of my
problems (which embarrassingly had nothing to do with JDOM.)

...and sure enough, in /etc/alternatives is a link to /usr/bin/java-vm, a
shell file that I didn't know existed. It was helpfully rearranging &
inserting all sorts of .jars in my classpath just before compiling or
executing & then quietly disappearing without leaving a trace. (I've now
added an "echo" so I'm aware of what is happening in there!)

Both the samples & my "hello JDOM" program now function beautifully.

Much Thanks to Amy, Steve, Jason & Phillip for getting me past this!
