MS-SQL JDBC Drivers deployment in SAP Netweaver 7.4

Hi,

Can some one share the technical procedure for deploying MS-SQL JDBC Drivers deployment in SAP Netweaver 7.4 in NWA. We have SAP PI 7.4 Dual stack system installation of Netweaver 7.4 components.

I have done the configuration setup as per the below mentioned link, but still with same error

Please advise.
