Hi,
I'd like to log some information from my BootStrap.groovy file to report
some configuration information and mark the transition from configuration
to execution phase of the application. This should appear in both the
logfile and on the console when I'm using development mode. My environment
consists of
Grails 2.3.8
Red Hat Enterprise Linux Workstation release 6.5
The trouble I'm having is seeing the BootStrap log.info output appear
only on the console when I run "grails run-app". I've provided two code
snippets to show what I'm doing. They would also be easy to plug into an
empty grails project (no domain classes or controllers need be created to
see the behavior I'm seeing). If you have any suggestions on my log4j
configuration I'd appreciate it a lot.
