Tutorials : Struts meets Swing (1) :

The DVD application

Once more we'll reuse my often-used DVD Library application--you may find it in the Struts article mentioned earlier, but I'll briefly run through it here.

It's an application that can be used to manage a collection of DVDs stored in an XML file. It can show all the DVDs on a List Page, and you may enter, update or delete a DVD on a Detail Page. The List Page looks like this:

- Figure 3: The List Page -

This is the first page you see, and the URL for it is (for a Tomcat installation on your own computer):

http://localhost:8080/dvdapp/list.do

When clicking on an "Id" you go to the Detail Page:

- Figure 4: The Detail Page -

The URL for this page is:

http://localhost:8080/dvdapp/detail.do?index=<dvd_number>

where dvd_number can be 0, 1, 2,

The dialog flow in the application is as follows:

The heart of the DVD application is the DVDmanager class, which keeps the DVDs in a JDOM tree-structure. The DVDManager reads the DVDs from an XML file, and can also write them back to this file with the save action. It's therefore an obvious choice to let the application return data to the Swing application in XML format.
