add a ChangeListener to the JTabbedPane object:


1.make this class implement changeListener
2  register change listener with tabs
    tabs.addChangeListener ( this );
3. implement ChageListener methods - there is one

  public void stateChanged ( ChangeEvent e )
 {
    if ( e.getSource ( ) == tabs ) {
     //call server method
   }
 }
  //probably no need to do a check though

Hi, get the model of your TabbedPane by calling getModel() method, then register ChangeListener to this model. Code would like smth like this:

JTabbedPane tabs = new JTabbedPane();
//form your tabs
tabs.getModel().addChangeListener(new ChangeListener()
{
   public void stateChanged(ChangeEvent e)
   {
      //do smth what you need
   }
})
