 3. Configure a data source in your application servlet or servlet container
 
 You may use absolutely anything: Tomcat, TomEE, Glassfish, Payara, you name it.

-This step may be optional depending on the container you are using. Most

-container (jstl-1.2.jar and jstl-impl-1.2.jar).

-In most cases you also have to put the postgresql JDBC driver into the library

 This is the most straight forward step. Just deploy the WAR file as you usually
 do in your application server.

 LightPIT can optionally detect the authenticated user. You may freely decide
 whether to enable authentication in your application server or put a web server
