while making database connection in oracle i have used classes12.jar which is of TYPE 4.
1) Who does provide this classes12.jar ?Is it database vendor like in this case oracle database vendor?
2)If classes12.jar is provided by database vendor then if tomorrow i change database then i will have to use .jar provided
by that database vendor.
so Is it correct that if i use MY-SQL then i will have to use let say mysql-connector-java-3.1.6-bin.jar which is i suppose
provided by My-SQL vendor?
