Retirieving cell data from a JTable

Squall

Im having trouble getting data from JTable cells,

Heres some of the relevant code,

Table creation ---

//Creates a custom table model
TableModel model = new DefaultTableModel(bookArray,headers)
{
//Makes the table read-only
public boolean isCellEditable(int x, int y)
{
return false;
}
};

//instantiates table using custom model
JTable table = new JTable(model);

// Set selection to first row
ListSelectionModel selectionModel table.getSelectionModel();

selectionModel.setSelectionInterval(0, 0);

//Allow only one item to be selected at once
selectionModel.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);

//Adds a selection listener to the table
selectionModel.addListSelectionListener(this);

---Handler
// Handler for list selection changes
public void valueChanged( ListSelectionEvent event )
{
ListSelectionModel lsm = (ListSelectionModel)event.getSource();

if (lsm.isSelectionEmpty()) {
JOptionPane.showMessageDialog(null,"Empty");
}
else
{
int selectedRow = lsm.getMinSelectionIndex();
JOptionPane.showMessageDialog(null,selectedColumn)
}

K so that all works ok, its returning the selected rows index but when i try to take the data from the 3 cells in the row nothing happens(well actually the command prompt fills with lots of ugly looking error code, first line says array out of bounds error)

Ive tryed a few different techniques

String author = (String)table.getModel().getValueAt(selectedRow,1);
String author = (String)table.getValueAt(selectedRow,1);

etc

But none of them seem to work. Any suggestions?
