Hi Gerrie,

The application is bootstrapped using an AppManifest - DomainAppAppManifest
in this case [1].   This references DomainAppApplicationModule which in
turn [2] references SimpleModule.  The set of modules that are loaded is
transitive, similar to Maven.  Each module is used to locate domain
services and entities from which the Isis metamodel is built.

When you say "deploy to tomcat", are you doing this through the IDE, or are
you doing a build using mvn and then taking the resultant .war file and
deploying that?  If it works in the latter then we know that the code isn't
wrong, just a stale computed classpath with the IDE.  If even mvn fails,
then there's a problem in the code itself.

If you wish, create an example on github to demonstrate the problem, and
describe how to reproduce in the README
