I had my logging.properties files mixed up. Now I am back where I started: I have logging from the hosting app but not either of the two apps I am hosting.
The logging from the app works both when I code the logging properties and when I supply them from the command line. What I am wondering is (and if so how) is the setup for logging different for the hosted apps? These are seemingly ignored. I can take the same two war files and put them on a Tomcat server and the logging works just fine.
