Not finding any pointers, asking here: is it possible to define environment
variables for a webapp?
If so, how?
You can only set them globally, for the Java process - not per web
application.
CGI creates a new process so can have a completely different set of
environment variables.
How about using the per web application JNDI context?

P.S.: Tomcat can manipulate the process' environment, e.g. in the case of CGI
execution. Here a
sample of the process' environment from some CGI-invocation on a Windows
