I have a web app running in Tomcat and it can be configured with various
parameters.
In particular, one of the parameters is a file path that defines where
various work files, uploaded files and logs are written to.
I have created a config file in this folder for other parameters but
ultimately something needs to define this path.
My first attempt had the path hard-coded but now I realise that's probably
not right, since I have to install the web app on Windows and Unix machines.
So then I checked the 'os.name' system property but that only gave me a Unix
version and a Windows version of the path - still ultimately hard-coded.
Where is the best place to configure this path so it's not hard coded in the
web app and is easy to configure when the app is deployed?
readonly => put it in the war
single app Tomcat => JVM arg -Dmy.config=...
Java 1.5 => set a variable and get it in web app with System getenv
fallback => OS neutral absolute path like "/mycfg"
