Follow-up post to this.
Up at 0400 and figured it was the perfect time to put a java build environment together so I installed JDK, ant and so forth and ran a build on the connector.
I've placed it in the lettuce install of cocoon (WEB-INF/lib to be precise).
Next, I'm going to uncomment the xep stanza in the root sitemap and restart Cocoon.
Fingers crossed...

*note: I did the build on my laptop, but this is java, right?
