Chris,
i needed to do the same & this is how i managed....
iSelectedTab is a class memnber & an int intialized to the index of the tab
initially selected....

   void myTabbedPane_stateChanged(ChangeEvent e)
   {
      switch (this.iSelectedTab)
      {
         case 0:
            if (YOUR_CONDITION_FOR_FAILOUR)
            {
               SHOW_MESSAGE_BOX

               this.myTabbedPane.setSelectedIndex (0);
               return;
            }
            break;

         case 1:
            if (YOUR_CONDITION_FOR_FAILOUR)
            {
               SHOW_MESSAGE_BOX

               this.myTabbedPane.setSelectedIndex (1);
               return;
            }

            break;

         case 2:
            if (YOUR_CONDITION_FOR_FAILOUR)
            {
               SHOW_MESSAGE_BOX

               this.myTabbedPane.setSelectedIndex (2);
               return;
            }

            break;
      }
      this.iSelectedTab = this.myTabbedPane.getSelectedIndex ();
   }


hope this helps
regards
