#jdbc_connection(unwrap = nil) ⇒ Java::JavaSql::Connection

Retrieve the raw java.sql.Connection object. The unwrap parameter is useful if an attempt to unwrap a pooled (JNDI) connection should be made - to really return the 'native' JDBC object.

Parameters:

  • unwrap (true, false) (defaults to: nil) —

    whether to unwrap the connection object

Returns:

  • (Java::JavaSql::Connection) —

    the JDBC connection
