Hi, I'm using TOS for Data Integration 5.3.1. I have imported projects built with TOS for Data Integration 5.1.0, the import was successful. But when I want to test my DB connections (Oracle Database 11gR2), I've got this error : "can not find class : oracle.jdbc.OracleDriver missing JDBC driver : ojdbc5.jar" I'm quite surprised because TOS is supposed to support Oracle. I downloaded ojdbc5.jar but how can I import this in TOS ? Thanks for your answers.
