MouseListener on JTable

Question

I am attempting to trap a mouse click on an editable JTable.
I have the following set up (csjt is the JTable):
csjt.addMouseListener ( new MouseAdapter()
     public void mouseClicked ( MouseEvent e )
          System.out.println ("in mouseclicked");
     public void mousePressed ( MouseEvent e )
          System.out.println ("in mousepressed");
     public void mouseReleased ( MouseEvent e )
          System.out.println ("in mousereleased");
Initially, I had the mouseClicked method, but that was not getting invoked when clicking in the table (specifically, when clicking on an editable column in the table). I added the mousePressed and mouseReleased methods, and the console lines do appear (as expected) when clicking between editable columns in the JTable. While I can certainly trap for either mousePressed or mouseReleased, I am wondering why mouseClicked is not getting invoked???
Thanks,

Hi Van,
i don't no why your mouseadapter doesn't respond to event, just
look at code bellow. it works with me.
import javax.swing.JTable;
import javax.swing.JScrollPane;
import javax.swing.JPanel;
import javax.swing.JFrame;
import java.awt.*;
import java.awt.event.*;
public class SimpleTableDemo extends JFrame {
public SimpleTableDemo() {
super("SimpleTableDemo");
Object[][] data = {
{"Mary", "Campione",
"Snowboarding", new Integer(5), new Boolean(false)},
{"Alison", "Huml",
"Rowing", new Integer(3), new Boolean(true)},
{"Kathy", "Walrath",
"Chasing toddlers", new Integer(2), new Boolean(false)},
{"Mark", "Andrews",
"Speed reading", new Integer(20), new Boolean(true)},
{"Angela", "Lih",
"Teaching high school", new Integer(4), new Boolean(false)}
String[] columnNames = {"First Name",
"Last Name",
"Sport",
"# of Years",
"Vegetarian"};
final JTable table = new JTable(data, columnNames);
table.setPreferredScrollableViewportSize(new Dimension(500, 70));
table.addMouseListener(new MouseAdapter() {
public void mouseClicked(MouseEvent e) {
printDebugData(table);
//Create the scroll pane and add the table to it.
JScrollPane scrollPane = new JScrollPane(table);
//Add the scroll pane to this window.
getContentPane().add(scrollPane, BorderLayout.CENTER);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
private void printDebugData(JTable table) {
int numRows = table.getRowCount();
int numCols = table.getColumnCount();
javax.swing.table.TableModel model = table.getModel();
System.out.println("Value of data: ");
for (int i=0; i < numRows; i++) {
System.out.print(" row " + i + ":");
for (int j=0; j < numCols; j++) {
System.out.print(" " + model.getValueAt(i, j));
System.out.println();
System.out.println("--------------------------");
public static void main(String[] args) {
SimpleTableDemo frame = new SimpleTableDemo();
frame.pack();
frame.setVisible(true);
