You can configure a JDBC driver for the entire TomEE application server or for a specific webapp. Regardless of which way you choose to do it, the configuration syntax is the same. NOTE: You can also configure a JDBC DataSource directly within an @Resource annotation but this is not recommended and is not covered here. See the…
