hi,
i got class not found exception of a small jdbc program in windows.

the program is like this[code=java]
import java.sql.*;
public class Db1
{
public static void main(String a[]) throws Exception
{
Class.forName(" oracle.jdbc.dri ver.OracleDrive r");
//Driver drv=new oracle.jdbc.dri ver.OracleDrive r();
//DriverManager.r egisterDriver(d rv);
Connection con=DriverManag er.getConnectio n("jdbc.oracle: thin:@localhost :1521:orcl","sc ott","tiger");
System.out.prin tln("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!
