if you use jdbc type (i) Driver so you no need to add any driver in websphare ,

you simply create DSN and use it locally , same we use java class,

if you use Type (2) and Type (4) so first go to admin consol then go to connection  then add driver there fill other information like connection size , user name password , max connection and connect it to your applications.

if you have any doubt so feel free to amil me.
