Hi Sameera,

Right now I am using the default Datasources component for my Database API,
it mandates to specify the Driver name. which is a limitation in tomcat.
Anjana will provide  patch so it will accommodate JDBC4 features.

@Anjana please provide more context if I have missed any.

Regards,
/Nuwan
