Focus with JTable - JDK 1.4

Question

Hi all, I wonder if there's anyone out there know about focus change on jdk1.4, please help me on this if you can:
with jdk 1.3, when I change focus between components on the same panel, I override this method of JTable to stop focus from being on table's rows only when the table has Focus since it does not move focus to the next component on the panel:
public boolean isManagingFocus() {
return false;
But when I use jdk 1.4 now, this method seems not work as expected anymore. The focus is now switch just between the rows when table has the focus and it does not move the focus to the next components on the panel when I hit TAB key.
If anyone knows how to fix this, please help me through. Anyhelp will be very appreciated.

Sorry it's late but here goes.
isManagingFocus is deprecated in 1.4 so it's probably best not to use that anyway. It's also called from the constructor of JComponent so if it uses instance variables you might get things like NullPointerException if you're not careful.
I think the recommended way to approach it is to set the focus traversal keys something like this
// get your table from somewhere
JTable table = new JTable();
// use java.awt.AWTKeyStroke to set up the appropriate focus
// traversal keys
AWTKeyStroke tab = AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB, 0);
AWTKeyStroke shiftTab = AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB, KeyEvent.SHIFT_DOWN_MASK);
AWTKeyStroke ctrlTab = AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB, KeyEvent.CTRL_DOWN_MASK);
AWTKeyStroke ctrlShiftTab = AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_TAB, KeyEvent.CTRL_DOWN_MASK | KeyEvent.SHIFT_DOWN_MASK);
// create a java.util.Set for forwards and backwards focus traversal
// keys. The actual concrete Set you use probably doesn't matter.
// I've used a java.util.HashSet
HashSet forwardKeys = new HashSet();
HashSet backwardKeys = new HashSet();
// add the appropriate keys to the appropriate sets
forwardKeys.add(tab);
forwardKeys.add(ctrlTab);
backwardKeys.add(shiftTab);
backwardKeys.add(ctrlShiftTab);
// set the focus traversal keys on the table.
table.setFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, forwardKeys);
table.setFocusTraversalKeys(KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS, backwardKeys);
