Okay. It seems it can not find the required classes.

See -> "How to Configure Webutil On Unix Platforms (Doc ID 290130.1)"

Jacob.jar should be there.

And as  the jacob.jar file is not an Oracle supplied jar file, it requires a self signed certificate to function properly with webutil. Check note named -> "How to Re-sign Expired .jar Files (Jacob, Icons, ...) and Extend the Self Signing Certificate(Doc ID 760815.1)" to see the steps for signing it, as well..
