From Database into JTable

Question

Hi!
I have a ResultSet from a database query (select * from table) and I plan to turn it into a Object[][] in order to satisfy one of the DefaultTableModel's constructor ("DefaultTableModel(Object[][] data, Object[] columnNames)") and place it in a JTable - how do I go about in doing this.
I tried this:
myJTable.setModel(new DefaultTableModel(getData(rs),columnNames));
private Object getData(ResultSet rs){
java.util.ArrayList<Object[]> mySets = new java.util.ArrayList<Object[]>();
try{
while(rs.next()){
Object[] row = {
rs.getString("column1"), rs.getString("column2"), new Boolean(false)
ResultSets.add(row);
catch(Exception e){
e.printStackTrace();
return mySets;
But got this error when I compiled:
cannot find symbol
symbol : constructor DefaultTableModel(java.lang.Object,java.lang.String[])
location: class javax.swing.table.DefaultTableModel
new DefaultTableModel(
1 error
BUILD FAILED (total time: 0 seconds)
I'm trying to do this because I would want to have my JTable to have a checkbox in it like what's shown in the Java tutorial's SimpleTableDemo.java.
Basically, am getting data directly from the database - those that are set to 1 is enabled and 0 to disabled, then represent those as check boxes in the JTable.
Thank you so much for your help!

Thanks calvino_ind!
I've managed to get your suggestion to work:
            while(rs.next()){
                for(int i = 0; i < row; i++){          
                    for(int j = 0; j < col; j++){
                        obj[i][j] = rs.getObject(j+1);
                    rs.next();
            }Issues:
I had to define the number of rows in order to initialize the Object's size:
            Object[][] obj = new Object[number of rows][number of columns];*column size can be retrieved from what's shown in previous post.
To get the number of rows I had to do this:
            while(rs.next()){ row++; }But in doing so, the cursor moves to the last row of the ResultSet. To move it back I had to execute this:
            rs.beforeFirst();Here's the whole section of the code that's been my concern:
    private Object[][] getData(ResultSet rs){
        Object[][] obj = null;
        int row = 0;
        int col = 0;
        ResultSetMetaData rsmd;
        try{
            rsmd = rs.getMetaData();
            while(rs.next()){ row++; }
            System.out.println(rs.getFetchSize());
            col = rsmd.getColumnCount();
            obj = new Object[row][col];
            rs.beforeFirst();
            while(rs.next()){
                for(int i = 0; i < row; i++){          
                    for(int j = 0; j < col; j++){
                        obj[i][j] = rs.getObject(j+1);
                    rs.next();
        }catch(Exception e){
            e.printStackTrace();
        return obj;
    }Now I did a little bit of fiddling around the forums, and came across a discussion that's it's not advisable to get the row count (second post of this link: http://forum.java.sun.com/thread.jspa?threadID=683676&messageID=3982010).
Anyone care to shed some more light into this?
Thanks!
