Clueless with Joe-E and Eclipse

Apologies if this is not the right place to ask. I'm trying to use
Joe-E and know nothing about Eclipse (it's like the second time I run
it). I followed the instructions at
http://code.google.com/p/joe-e/wiki/GettingStarted up to the point
where the plug-in is downloaded and Eclipse restarts, and then...
Nothing. There is no Joe-E pane in the Eclipse preferences, and no way
to "enable Joe-E verifier" in projects regardless of the CLASSPATH
settings.

I'd be happy with a solution that involves running the verifier
directly (as an Ant task or shell command), as I'm more of an Emacs
guy anyway. I hereby promise to add documentation into the Joe-E wiki
if appropriate.

I'm using Eclipse 3.4.1 (Build id: M20080911-1700) under Mac OS X for
Intel version 10.5.5 (9F33). Any help greatly appreciated.
