This Tomcat-based micro-service takes an SQL query as a GET parameter, runs it on an Informix database through the Informix JDBC driver, and returns the results as a CSV formatted plain text response.
Tomcat is configured to serve the app at the http root on port 80.
Use the get parameter ?sql= to pass SQL queries.
NB: the database connection is configured as read-only.
