Connecting to a dsn

Question

so far, i'm connecting directly to oracle using jdbc driver and this is
my connection string which works just fine
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection("jdbc:oracle:thin:@servername-1:portname:sid","username", "password");now i have a DSN from an RDB and i was wondering how the connection string would be to connect to a DSN and how the driver connection string would also be
also, what driver should be used? would that need a jdbc-odbc driver?
thanks

Answer 1

my development environment is in windows but when this gets deployed to production, it will be deployed in linux.
so it will not work then?
this is my class:
package connection;
import java.sql.*;
import java.io.*;
public class WksDBConnection
     private Connection con;
     public WksDBConnection()
          try
              Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
              con = DriverManager.getConnection("jdbc:oracle:DSNName","usernme", "pswrd" );
        catch (Exception e)
             e.printStackTrace();
     public Connection getConnection()
          return con;
     public void close()
          try
               con.close();
          catch(Exception e)
               e.printStackTrace();
     public static void main(String[] args)
          Connection con;
          try
               con = new WksDBConnection().getConnection();
               Statement stmt = con.createStatement();
                ResultSet rs = stmt.executeQuery("SELECT count(*) FROM WLOT");
                rs.next();
                int num = rs.getInt(1);
                System.out.println(num);
                 con.close();
              rs.close();
              stmt.close();
         catch (SQLException se)
                System.out.println("SQL Exception: " + se.getMessage() + "not connected");
                se.printStackTrace(System.out);
}
