I've made some progress: each component appears to be logging successfully.
The config file for each component had to be placed in the
following directories:


It still isn't clear to me how/where grouper.home is defined for each
component, so logfiles have been set with absolute paths.

Each component's file was based off of the provided
sample grouper-api/conf/ where each of


was set to go to a logfile dedicated for that component. E.g.:


However, everything logged (api, ui, ws) is going to grouper-api.log.

How do I differentiate the output for each component? It's not clear
from looking at the subset in grouper-ui/
what the relevant properties are. I must be missing something though.
