Hi Paul, I even tried oracle.jdbc.driver.OracleDriver,I have downloaded the latest jars like classes12.jar,ojdbc14.jar for this driver, still the exception persists. Can you please be more specific as to which driver implements or supports the method getBlob().
Get it where you got your other driver classes. Looking at the JavaDocs for the v8.1.7 thin driver though, the getBlob() method is not flagged as unsupported, so you shouldn't have to use a newer version of the driver. If you post the code you use to get your connection, perhaps we can see where you are going wrong.
