So, I'm unable to set the env variables.
Probably the best place to implement something would be as a context parameter (http://tomcat.apache.org/tomcat-6.0-doc/config/context.html#Context_Parameters). We could then fairly simply add yet another prioritized source of DHIS_HOME: (i) check for context parameter called DHIS2_HOME; failing which (ii) check for system property called dhis2.home; failing which (III) check for env variable DHIS2_HOME. (the final fallback on linux is to use /opt/dhis2) The context should be configurable by the Paas provider. Any thoughts? Should be a quick blueprint + some few lines of code + testing.
