-/**
- * Required to still have a working legacy "classic" WAR.
- *
- * Configuration just adds the JNDI-based DataSource lookup to its
- * AbstractApplicationConfiguration.
- *
- * This (intentionally) only configures the original (pre-Spring Boot &amp;
- * MariaDB4j) fineract Spring Beans, and does NOT include the embedded Tomcat
- * (incl. TomcatSSLConfiguration) nor the MariaDB4jSetupService or
- * MariaDB4jDataSourceConfiguration, and not even the DataSourceConfiguration
- * (as it uses "classic" JNDI) - we want the WAR to "work like before".
