Mouselistner is not working with jtable in the browser

Question

Hi
I am having a problem with jTable.
I added a mouselistener to table header to sort table but when i run that applet from my netbean ide it works fine but when i run that applet in my browser it doesn't work, i have tested, its not even generate mouseclick event .Please help me guys.
I call this function after calling initComponents() method of JApplet.
public void setTableAction()
//set mouselistener to sort table on click of table header
final JTableHeader head= jTable1.getTableHeader();
head.addMouseListener(new java.awt.event.MouseAdapter()
public void mouseClicked(java.awt.event.MouseEvent evt)
Vector data= ((DefaultTableModel)jTable1.getModel ()).getDataVector();
sortTable(data, head.columnAtPoint(evt.getPoint()));
//set action map to change the default action performed for enter key pressed
InputMap imap = jTable1.getInputMap(JTable.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
KeyStroke enterKey = KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0);
KeyStroke tabKey = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0);
final Action oldAction= jTable1.getActionMap().get(imap.get(tabKey)); // get map to set enter key.
imap.put(enterKey, "enter"); // set enter key
Action newAction = new AbstractAction(){
public void actionPerformed(ActionEvent e) {
oldAction.actionPerformed(e);
JTable table= (JTable)e.getSource();
table.changeSelection(0,0,false,false);
if(table.isCellEditable(0,0))
String sTemp= (String)table.getValueAt(0,0);
if(sTemp.length()>0) {
if(bRenewItem)
retrieveRcodeDetails("",sTemp);
else
processRCodeDetails(sTemp, e);
}else
table.editCellAt(0,0);
jTable1.getActionMap().put("enter", newAction);
jTable1.setPreferredScrollableViewportSize(jTable1.getPreferredSize());
}

Hi,
I also am using the Bépo layout with an encrypted drive and encountered the same problem: the Return key does not work.
It seems to work fine if you use the fr-bepo-latin9 keymap.
# /etc/vconsole.conf
KEYMAP=fr-bepo-latin9
But I also looked at the files /usr/share/kbd/keymaps/i386/bepo/fr-bepo.map.gz and /usr/share/kbd/keymaps/i386/bepo/fr-bepo-latin9.map.gz (you can open gzipped files in vim directly). fr-bepo-latin9.map.gz defines keycode 28 (Return) but fr-bepo.map.gz does not.
I modified fr-bepo.map.gz:
# vim /usr/share/kbd/keymaps/i386/bepo/fr-bepo.map.gz # Append that line : "keycode 28 = Return".
# mkinitcpio -p linux # Rebuild the initramfs.
The Return key now works, but the Backspace (14, "Delete") and Shift (54) keys don’t work. I found that both the cf.map.gz (french canadian layout) and fr-bepo-latin9.map.gz files define those keycodes as well as other non-printing keys so I copied the following lines from fr-bepo-latin9.map.gz to fr-bepo.map.gz:
keycode 1 = Escape Escape
keycode 14 = Delete Delete
keycode 15 = Tab Tab
keycode 28 = Return
keycode 29 = Control
keycode 42 = Shift
keycode 54 = Shift
keycode 56 = Alt
keycode 58 = Caps_Lock
keycode 97 = Control
It works! Don’t forget to rebuild the initramfs after you change the keymap file.
# mkinitcpio -p linux
I will send a message to the kbd and bépo projects mailing lists and report back.
