I have my DB details stored in a properties files. When I tried to replace them with Openshift environment variables they didn't get replaced. eg:
#Updated at Wed Nov 05 14:59:29 SGT 2014 #Wed Nov 05 14:59:29 SGT 2014 database.driverClassName=com.mysql.jdbc.Driver database.url=jdbc\:mysql\://$OPENSHIFT_MYSQL_DB_HOST\:$OPENSHIFT_MYSQL_DB_PORT/PIP database.username=$OPENSHIFT_MYSQL_DB_USERNAME database.password=$OPENSHIFT_MYSQL_DB_PASSWORD
