May 24, at It was pretty easy to use and deploy as well just include driver’s jar in classpath and you are ready. When Java first came out, this was a useful driver because most databases only supported ODBC access but now this type of driver is recommended only for experimental use or when no other alternative is available. This is also called type 2 driver and its slightly better than type 1 JDBC driver. Thanks December 31, at 5: As a result, you need some knowledge of the application server’s configuration in order to effectively use this driver type. The distinctive characteristic of type 2 jdbc drivers are that Type 2 drivers convert JDBC calls into database-specific calls i.
