Configuration Issue with BI system for VC

Hi Experts,

I am going to configura BI System but I am getting some problem..when I want to use BI wizard in Visual Composer...

I am using EP 7.0

Error2305cannot retrieve catalogs and schemas...etc..

when I already pass JDBC connection...

Connection URL: jdbc:sap:sqlserver://epsans1.xxxxxxxx.com50000;DatabaseName=EP7

Driver Class Name: com.sap.portals.jdbc.sqlserver.ojdbc14.jar

Is I am missing some parameter or what should i do ?

Please help me out.

Regards,

Iqbal
