Pentaho Job Scheduler SQl connection Error

Pentaho Job Scheduler SQl connection Error

I am new to the pentaho software and researching it for use in my company.
WHEN i run the transformation that connects to my database ON the DATA
integration design VIEW it runs alright.
Yet when the same transformation is scheduled, I see the error below in
the DI logs
I have put the following Mysql connector FILE
mysql-connector-java-5.1.26-bin.jar INTO the folders below AS indicated IN
the forum.
C:\Program Files\pentaho\design-tools\DATA-integration\lib C:\Program
Files\pentaho\design-tools\DATA-integration\libtext
I have restarted the pc several times but error keeps showing.
are you able TO make a suggestion AS TO how this issue can be resolved?
