Oracle JDBC problem with WebPortal Version 4.2.5 - Could not register database driver...

KNIME Server
1

I have a Database Reader node that picks up some data from an Oracle DB. It works when run from the client. But if I "Reset" this Database Reader node (so that the yellow light appears) before I publish the WF to the server, then, when I run the WF from the WebPortal, I got the following error: Execute failed: org.knime.core.node.InvalidSettingsException: Could not register database driver "oracle.jdbc.driver.OracleDriver", reason: oracle.jdbc.driver.OracleDriver.

The WF works also from the server if I run within "KNINE Analytics Platform" (Desktop App). I have configured it to make use of the ojdbc7.jar library.

P.S. More in general, should I "Reset" nodes before publishing WFs to the server and can this have an effect on the final result?

Thanks,
Fabio

I had to export my "preferences" and put this .epf file under /config.
