The URL and driver are correct,
What is the problem?

I got a simular error on NT a few months ago.
1. Do you have the oracle jdbc driver in you classpath?
2. Has Net8 been stup correctly.
3. Is your URL refering to the thin client or OCL driver.
1. copy of path
2. copy of classpaht
3. copy of Class.forNames
4. copy of your URL

hi, Monty,
Thanks for your reply. It is not classpath or drive problem, as another program runs OK. Here is the code:
import java.sql.*;
public class JdbcTest1 {
public void doTest(){
try{ Class.forName("oracle.jdbc.driver.OracleDriver");
Connection con =DriverManager.getConnection( "jdbc racle:thin:@geodel.newcs.uwindsor.ca:1521:CS01", "simon", "p548") ;
Statement stmt = con.createStatement();
System.out.println("Table Created?"+ stmt.executeUpdate( "create table mytable (sno integer, name varchar(20) )")); System.out.println("Inserted?"+ stmt.executeUpdate("insert into mytable values (1, 'Silly')"));
System.out.println("Inserted?"+stmt.executeUpdate ("insert into mytable values (2, 'Ken')"));
ResultSet rs = stmt.executeQuery("select * from mytable");
while ( rs.next() ){
System.out.println("SNO==>" + rs.getInt("sno")+"\n");
System.out.println("SNO ==>"+ rs.getString("name")+"\n");
}catch (Exception e){
System.out.println("Error Creating Record");
public static void main( String[] args ) {
JdbcTest1 test = new JdbcTest1();
