IS 4.6 Connecting to a Oracle DB through JDBC


I am getting the following error when I try to connect to a Oracle 8 DB.

Could not connect: Link Error: no ocijdbc9 (ocijdbc9.dll) in java.library.path

I have the following settings

DB URL : jdbc:oracle:oci8:@EFEMCO
DB Driver: oracle.jdbc.driver.OracleDriver

The driver has been loaded, but it looks for a ocijdbc9.dll, which I don�t have.

I have on c:\IS directory\lib\jars

The OracleDriver.class file contains ocijdbc9.
Do I have the right file?

Has anybody experienced this problem before?
