Mysql DataBase connectivity with PI 7.1

Dear Experts,

        I need to connect Mysql DB table to access the data using PI 7.1 and pass it to ECC RFC.

I have configured the sender JDBC channel details as below

JDBC Driver : com.mysql.jdbc.Driver

Connection : jdbc:mysql://<Server>:<port>/<database>

But it showing the below error while starting my Sender channel in RWB.

We already install the above driver  com.mysql.jdbc.Driver in PI again it shows the same error.

Kindly help to resolve this issue.

Best Regards,
