Okay, Steve Meyer figured it out. The app started up just fine, but the first time the "Inbox" class was called, it called it's superclass which has a static variable that loads a set of EOs from the database. That DB connection failed, which left the superclass uninitialized and therefor basically corrupt, and therefor the NoClassDefFoundError.
I think we'll be digging around looking for more issues like this. Soon. Dave PS, Sorry about the lack of stack trace.
