Hi Dan, That all makes perfect sense, thank you!
However, I see a possible issue with the order in which things get executed with this approach. EC can be set to create a ColdSpring.xml stub file for inclusion in the main ColdSpring.xml file, this stub creating a config bean based on the configuration data set in the environment.xml.cfm file. I'm thinking that the beans will already have been instantiated from ColdSpring.xml by the time onApplicationStart gets called, since we'd be using the EnvironmentService bean within the onApplicationStart function. So this would execute, and the stub file would get generated, but it's too late at that point to get ColdSpring to instantiate the config bean defined in the stub. Does that make any sense? Mike.
