This sub-process is invoked by the method is used to reorganize the inventory to ensure that books have been assigned to the right categories.Therefore, after updating the data model, you can guarantee that any category without books has been removed and any new category has been added.View image at full size After building a framework that monitors data changes on the server side, you need to find a way to update the data model and create dynamic GUI elements if the bean is to be notified of any changes.This process takes place inside the managed bean (see the Bean layer of Figure 2) and can be divided into two sub-processes: updating the data model and creating GUI elements.When you next save changes to your map file, the Auto Save as Web dialog box appears, giving you the following choices.Does not update your Web page with any changes saved to the map file during the current session.



Updates your Web page with any changes that you save to your map file.Swing already provides a mature way to automatically update the GUI based solely on the internal data status, but JSF does not have good support for refreshing the GUI based on a request from the server side.If you check the standard life cycle of JSF, you will find that the user normally needs to produce an event on the Web page (by clicking a button, for example) to invoke the GUI refresh.At this time, JSF has no good solution to this problem.

Although you may be familiar with Java Swing applications such as "clock," in which data changes prompt GUI updates, or you might have read the implementation details of such applications in some basic Swing development guides, this approach will not work with my scenarios.

The inventory information such as book categories and the number of books in each category is displayed in the Web home page (see Figure 1).
