The applicationContext XML File, what you see under WEB-INF, is NOT
the applicationContext of the an Grails Application, its the PARENT
applicationContext which bootstraps the infrastructure of a grails app
(incl. GrailsApplication, PluginManager etc.)
The applicationContext of an Grails app is dynamically/
programmatically constructured by the above infrastructure on startup
process. If something goes wrong on this process, i think, you may use
a remote debugger to connect to the JEE Server and see whats going on
there.
Have Luck!
