Question

Hello
I have made tables in oracle and im tryin g 2 connect these tables to java where i have made forms. i havent downloaded any driver but i think when i installed Oracle 8.1.7 it has jdbc drivers too. now i dont know which driver it is, thin, internal, etc. im tryin to run a separate code which checks the connection. It keeps giving an error saying that the" specified driver does not exist". but i dont know wot to do coz i dont know which driver it is.

}i tried it but i still get the same error msg. tht the specified driver does not exist.
i have in my classpath - CLASSPATH=.;[ORACLE_HOME]jdbc\lib\classes12.zip
and in my variable ORACLE_HOME AND it s value - C:\oracle\ora81
the error that i get is
