درخواست کد جاوا

ایجاد کلاسی که اطلاعات رو از دیتابیس بخونه و اطلاعات خوانده شده رو داخل یک یا چند jsp بشه خروجی گرفت.
در واقع روش MVC انجام بشه توش.

یک کد رو خودم نوشتم مشکلش کجاست.

package panel;

import java.sql.*;
import java.util.ArrayList;
/**

public class DBHandler {

private Connection cn;

public DBHandler() throws SQLException {

try {
Class.forName("com.mysql.jdbc.Driver");
cn = DriverManager.getConnection("jdbc:mysql://localhost:3306/siwa", "root", "");
}
catch (Exception ex){
throw new SQLException("data source has not found", ex);
}
}

public void koko() throws ClassNotFoundException, SQLException {
ArrayList retAry = new ArrayList();
String getQuery = "SELECT * FROM pagenew";
try (PreparedStatement ps = cn.prepareStatement(getQuery)) {
ResultSet result = ps.executeQuery();
while (result.next()) {
String title = result.getString("title");
String content = result.getString("content");
String time = result.getString("time");
Ites it = new Ites(title,content,time);
retAry.add(it);
}
result.close();
}
catch (SQLException ex) {
System.out.println("ERoor");
}
}

}
