Problems with DefaultTableModel

Question

Hi everyone...
I m trying to use DefaultTable model to present data from my database, but i cannot get it to work or better said show any data what so ever...
this is the sample of my code...
//just a snippet of my code...just the part where i have problems with
JTable dataTable=new JTable();
        DefaultTableModel tableModel=new DefaultTableModel();       
        tableModel.setColumnIdentifiers(amarnaTableNames);       
        try{
            CallableStatement calling=myConnectionClass.returnConnection().prepareCall(selectQuery);
            ResultSet result=calling.executeQuery();
            ResultSetMetaData metaResult=result.getMetaData();
            Object[] myData;
            while(result.next()){
                myData=new Object[columnNumber];
                for(int i=0;i<amarnaTableNames.length;i++){
                    amarnaData=result.getObject(i+1);
System.out.print(amarnaData[i]);//just to see if i get anything from my database...and i do
tableModel.addRow(amarnaData);
catch(SQLException ex){
dataTable.setModel(tableModel);//but when i try to show ma JTable...i cannot get nothing though i know i get the neccessary data from my database
So basically what i would like, if someone can please help me, is if there is any good tutorials or at least a simple example on how to use DefaultTableModel...
Thnx everyone

Answer 1

or at least a simple example on how to use DefaultTableModel..Here is my simple example:

And here is another example of building the TableModel from a ResultSet:

How do you know the problem is with the TableModel. Do you add the table to the GUI? Maybe you define the table twice, once when you add it to the GUI and once in the code you just posted.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.
