I am adding functionality to a tutorial which is a JDesktopApplication(Netbeans6.1)using Entity class from databases with Persistence unit and entitymanager.

I have components in place.

Can someone help me find out if there is a bean that fires the actionperformed methods?
Ican't figure out were it is.

I need to study this bean to learn how to find out if actionlisterners are implicitly added to components or if I need to learn how to explicitly call method from this bean.

I have a packaged netbeans project (JDesktopApplication) and I need to understand the bean binding proceedures if there is one.

If I am adding components and queries to a JDesktopApplication (database) would it be safe to say I need a BenaInfo class extending SimpleBeanInfo and for lack of a better term sync them?
