Can I pass an Object THROUGH to a LISTENER?

Question

I created a class called FuncSelect(), whose constructor takes a JDBCClass object as an argument.
public FuncSelect( JDBCClass dbApp) {
}Passing in this object allows FuncSelect() to reference JDBCClass's Session object and various methods.
FuncSelect implements a listener, which in turn calls method postUpdate(), which needs to reference the dbApp.Session object -- however, I'm getting hung up trying to figure out how pass dbApp through to the listener:
    class OKListener implements ActionListener {
        public void actionPerformed(ActionEvent e ) {
            postUpdate() ;  // <--- need to pass dbApp to this method!!!!
    }Confused? Again need to pass dbApp object as follows:
FuncSelect(JDBCClass dbApp) --> OKListener( ActionEvent e, JDBCClass dbApp) --> postUpdate(JDBCClass dbApp ).
Do I need an abstract class for this? Any samples out there?
Thanks for any assistance.

There's nothing that says that your listener can't have more than just an actionPerformed method. Add a method (or a constructor) to your listener that accepts a JDBCClass object just like the FuncSelect class does.
class OKListener implements ActionListener {
  private JDBCClass dbApp = null;
  public OKListener() { super(); }
  public OKListener (JDBCClass dbApp) {
    super();
    this.dbApp = dbApp;
   public void actionPerformed(ActionEvent e ) {
   postUpdate(dbApp) ;  // <--- need to pass dbApp to this method!!!!       
}
