As Michael mentioned, you want to implement a ChangeListener. WHen I did
that I defined the following:

public void stateChanged(ChangeEvent e) {
try {
if (ldapTabs.getSelectedIndex() == 2 ||
ldapTabs.getSelectedIndex() == 0) {
menuItemReferrals.setEnabled(true);
}
else if (ldapTabs.getSelectedIndex() == 1) {
menuItemReferrals.setEnabled(false);
}
} catch (NullPointerException nullEx) {}
}

That let's me disable an option on the menu whenever a certain tab has
been selected as the active tab. I added the JFrame the tab was in as
the ChangeListener for the JTabbedPane.
