Hi..I am trying to connect oracle which is on my pc.i am using oracle 9i.
i am creating 1 customer table & trying to display it.

import java.sql.*;
import java.net.*;
public class JdbcDemo{
	public static void main(String args[]){
		Driver d;
		Connection con;
		Statement stmt ;
		ResultSet rs;

		try{
   			d=(Driver)Class.forName("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
      			System.out.println("Got driver");
   			con =DriverManager.getConnection("jdbc:odbc:thin:@localhost:1521:XE","scott","tiger");
   		//	con =DriverManager.getConnection("jdbc:oracle:thin:2030:oracle","scott","tiger");
  			
  			System.out.println("Got Connection");
  		
  			stmt = con.createStatement();
			System.out.println("Statement object created");
   			rs= stmt.executeQuery("select * from customer");
   			while(rs.next()){
       		
					System.out.println(rs.getString(1));
       				System.out.println(rs.getString(2));												
					System.out.println(rs.getString(1)+"  "+rs.getString(2));
			}
		}
		catch(IllegalAccessException e){
			System.out.println("in IllegalAccess exception");
			e.printStackTrace( System.out );


		}
		catch(ClassNotFoundException e){
			System.out.println("in class not Found exception");
			e.printStackTrace( System.out );

		}
		catch(SQLException e){
			System.out.println("in SQLException exception");
			e.printStackTrace( System.out );

		}
		catch(Exception e){
			System.out.println("in exception");
			e.printStackTrace( System.out );

		}
	}
}

It gives Error.....
