Does anyone have experience with a multi-project Grails app (where two or more of the sub-projects are full Grails apps) running on a single/shared embedded Tomcat server? I found some information about potentially using the "Gretty" plugin, but was looking for general advice/resources to help figure out how to best get all of the Grails apps in a multi-project build to run under a single, embedded Tomcat server.
