create jdbc connection from idt to Oracle DB 12c

Hello,

I am creating this discussion because I tried a lot of things without success.

I am trying to create a jdbc connection to an Oracle database 12c.

I am using IDT BI 4.1 SP6 to reach a BI 4.1 server with SP6 patch1.

I always have this error message : Java Class not found in classpath : oracle.jdbc.OracleDriver.

I did add ojdbc7.jar file in a folder noticed in oracle.sbo file.

I tried also recommendation from this website JDBC connectivity in SAP BI 4.0 | Irfan's World

If any one can help me it would be great.

Thanks

Antoine
