Hi Neil: Thanks for the answer. I do have the event bundle active, I added a plug-in project from an existing JAR file (event1.0.100.jar or something like that), and the bundle is active (Event 1.0.0) . when I put the SS command. I downloaded the JAR from here: http://www.jarvana.com/jarvana/browse/org/eclipse/equinox/event/
I also added to the dependencies in both generator and listener's MANIFEST file. The EventPoster is ACTIVE, but it has nothing in the tracker yet. The listener is still "RESOLVED" and gives me exceptions when I try to run it.
