You're *almost* right on, as it turns out; adding the jar files to the
classpath explicitly does indeed make it work. A little further poking
showed me, however, that it's jde.util.JdeUtilities which isn't taking
account of the extension dirs, not the bsh. The patch below fixes
this. It makes *no* attempt to do anything with download extensions
(which I'm not convinced I understand all the ramifications of) but it
does handle installed extensions.
I did perpetuate the assumption in JdeUtilities.java that jar files will
have file extensions of ".zip" or ".jar". I don't know that that
assumption is always guaranteed to hold, but I also don't know any sane
programmers who'd call their jar files anything else.
Peace,
