Can't connect to oracle database using jdbc thin drivers

I am trying to connect to Oracle Database 10 XE using Oracle thin drivers, but I cannot get it. I even added drivers to my classpath at compile time.

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.Properties;

public class Connectivity {
    public static void main(String args[]) throws SQLException {
        String url = "jdbc:oracle:thin:@localhost:1521:XE";
        Properties props = new Properties();

        props.setProperty("user", "SYSTEM");
        props.setProperty("password", "iiita");

        try {
            Class.forName ("oracle.jdbc.driver.OracleDriver");
        } catch (ClassNotFoundException e) {
            System.out.println(e.getMessage());
        }
        Connection conn = DriverManager.getConnection(url,props);
        String sql ="select sysdate as current_day from dual";

        PreparedStatement preStatement = conn.prepareStatement(sql);

        ResultSet result = preStatement.executeQuery();

        while(result.next()){
            System.out.println("Current Date from Oracle : " +  result.getString("current_day"));
        }

        System.out.println("done");

    }
}

      

        
        
        
      

    

This code gives the following error when run

Exception in thread "main" java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@localhost:1521/XE
