  When the hibernate.connection.datasource property value is resolved to a javax.naming.Context object, this configuration property defines the JNDI name used to locate the DataSource used for fetching the initial Connection which is used to access to the database metadata of the underlying database(s) (in situations where we do not have a tenant id, like startup processing). </td> </tr> </tbody> </table> </div>
