SQL query into JTable - arraylist

Question

I've found one totally working query, which gets columns and their data from Oracle DB and puts the output in console printout.
I've spent 3 hours trying to display this data in Swing JTable.
When I am trying to bind data with JTable:
jTable1.setModel(new javax.swing.table.DefaultTableModel(
data, header
));
it keeps telling me that constructor is invalid. That's true, because I need arrays [] and [][] to make that. Any ideas how this can be implemented?
Here is the original query:
package com.javacoderanch.example.sql;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.ResultSetMetaData;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.ArrayList;
public class MetadataColumnExample {
private static final String DRIVER = "oracle.jdbc.OracleDriver";
private static final String URL = "jdbc:oracle:thin:#//XXX";
private static final String USERNAME = "XXX";
private static final String PASSWORD = "XXX";
public static void main(String[] args) throws Exception {
Connection connection = null;
try {
//
// As the usual ritual, load the driver class and get connection
// from database.
//
Class.forName(DRIVER);
connection = DriverManager.getConnection(URL, USERNAME, PASSWORD);
//
// In the statement below we'll select all records from users table
// and then try to find all the columns it has.
//
Statement statement = connection.createStatement();
ResultSet resultSet = statement.executeQuery("select *\n"
+ "from booking\n"
+ "where TRACKING_NUMBER = 1000001741");
//
// The ResultSetMetaData is where all metadata related information
// for a result set is stored.
//
ResultSetMetaData metadata = resultSet.getMetaData();
int columnCount = metadata.getColumnCount();
//
// To get the column names we do a loop for a number of column count
// returned above. And please remember a JDBC operation is 1-indexed
// so every index begin from 1 not 0 as in array.
//
ArrayList<String> columns = new ArrayList<String>();
for (int i = 1; i < columnCount; i++) {
String columnName = metadata.getColumnName(i);
columns.add(columnName);
}
//
// Later we use the collected column names to get the value of the
// column it self.
//
while (resultSet.next()) {
for (String columnName : columns) {
String value = resultSet.getString(columnName);
System.out.println(columnName + " = " + value);
}
}
} catch (SQLException e) {
e.printStackTrace();
} finally {
connection.close();
}
}
}

Ok I found a bit better way adding SQL query to JTable without even using the ArrayList. Maybe will be helpful for someone, completely working:
import java.awt.*;
import javax.swing.*;
import java.sql.*;
import java.awt.image.BufferedImage;
public class report extends JFrame {
PreparedStatement ps;
Connection con;
ResultSet rs;
Statement st;
JLabel l1;
String bn;
int bid;
Date d1, d2;
int rows = 0;
Object data1[][];
JScrollPane scroller;
JTable table;
public report() {
Container cp = getContentPane();
cp.setLayout(new BorderLayout());
setSize(600, 600);
setLocation(50, 50);
setLayout(new BorderLayout());
setTitle("Library Report");
try {
Class.forName("oracle.jdbc.OracleDriver");
con = DriverManager.getConnection("jdbc:oracle:thin:#XXXXX", "XXXXX", "XXXXX");
} catch (Exception e) {
}
try {
/*
* JDBC 2.0 provides a way to retrieve a rowcount from a ResultSet without having to scan through all the rows
* So we add TYPE_SCROLL_INSENSITIVE & CONCUR_READ_ONLY
*/
st = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); //Creating Statement Object
} catch (SQLException sqlex) {
System.out.println("!!!###");
}
try {
rs = st.executeQuery("select TRACKING_NUMBER, INCO_TERM_CODE, MODE_OF_TRANSPORT\n"
+ "from salog.booking\n"
+ "where rownum < 5");
// Counting rows
rs.last();
int rows = rs.getRow();
rs.beforeFirst();
System.out.println("cc " + rows);
ResultSetMetaData metaData = rs.getMetaData();
int colummm = metaData.getColumnCount();
System.out.println("colms =" + colummm);
Object[] Colheads = {"BookId", "BookName", "rtyry"};
if (Colheads.length != colummm) {
// System.out.println("EPT!!");
JOptionPane.showMessageDialog(rootPane, "Incorrect Column Headers quantity listed in array! The program will now exit.", "System Error", JOptionPane.ERROR_MESSAGE);
System.exit(0);
}
data1 = new Object[rows][Colheads.length];
for (int i1 = 0; i1 < rows; i1++) {
rs.next();
for (int j1 = 0; j1 < Colheads.length; j1++) {
data1[i1][j1] = rs.getString(j1 + 1);
}
}
JTable table = new JTable(data1, Colheads);
JScrollPane jsp = new JScrollPane(table);
getContentPane().add(jsp);
} catch (Exception e) {
}
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String args[]) {
JFrame frm = new report();
frm.setSize(600, 600);
frm.setLocation(50, 50);
BufferedImage image = null;
frm.setIconImage(image);
frm.setVisible(true);
frm.show();
}
}
