27  * Scriptella driver for JNDI datasources.
28  * <p>This driver relies on {@link scriptella.jdbc.GenericDriver} functionality.
29  * <p><em>Note:</em>Currently this driver does not support JTA transactions
30  * and simply use connections provided by datasource.
31  * In this case new-tx has no effect if code is runned inside a transaction.
32  * <p>For configuration details and examples see <a HREF="package-summary.html">overview page</a>.
