I found this link on SO website, which suggests to configureconfiguring few parameters in datasourcedata source config https://stackoverflow.com/questions/16331959/java-sql-sqlexception-already-closed
However, I am unable to find any datasource config/XML file for Content Service.
My confusions/Queries:
Content service uses/is itself Apache Tomcat App ?
Does this service has files like: server.xml ? Like we have in an apache tomcat app ?
