java - How do I manually invoke an Action in swing?

Question

For the life of me I cannot seem to find details on Java Swing Actions :'( When I came across them I immediately realised their usefulness. So far it's all been easy to work with. Now I'm stuck with one little thing: How do I run them manually? I mean by code? Note that I am building the GUI using Netbeans (if that makes any difference). I've come as far as:

Application a = Application.getInstance(JPADemoApp.class);
ApplicationContext ctx = a.getContext();
ActionMap am = ctx.getActionMap(JPADemoView.class, this.app);
Action act = am.get("fetchOrders");

( I wrote all on separate lines to simplify debugging )

So now I have a valid reference to the Action. Now how do I run it?

You can simply invoke the action event's method directly:

for(ActionListener a: buttonExample.getActionListeners()) {
    a.actionPerformed(new ActionEvent(this, ActionEvent.ACTION_PERFORMED, null) {
          //Nothing need go here, the actionPerformed method (with the
          //above arguments) will trigger the respective listener
    });
}
