the program is like this

import java.sql.*;
public class Db1
{         
        public static void main(String a[]) throws Exception
        {
       Class.forName("oracle.jdbc.driver.OracleDriver");
    //Driver  drv=new oracle.jdbc.driver.OracleDriver();
    //DriverManager.registerDriver(drv);
        Connection con=DriverManager.getConnection("jdbc.oracle:thin:@localhost:1521:orcl","scott","tiger");
        System.out.println("concls->"+con.getClass());
 
        }
}
 and the problem is like this
 
 
E:\work>javac Db1.java
Db1.java:21: cannot find symbol

I already set the classpath

But what did you set it to? Does it include the driver's jar? I don't think so!

the necessary jar file for my jdbc driver is classes12.jar
i copied tht into my working directory.. like this

E:\work\classes 12.jar

It doesn't matter where you put library jars, like your driver jar, as long as the jar is on the classpath!
