thin driver is type 4 driver which comes with oracle database.
Its class is oracle.jdbc.driver.OracleDriver
The classname oracle.jdbc.driver.OracleDriver is deprecated, sometime after Oracle 8i; the preferred name is now oracle.jdbc.OracleDriver, although the old name continues to work with the most recent releases of the driver.
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
