A demo application
I admit I've used the DVD library application before: for
example in my article "Coding your second Jakarta Struts Application". It's a
classical list-detail application and it's great for
demonstrations since it's so simple, still it illustrates many
important aspects of a web application. It has these two
pages:
Figure 2: The List page
Figure 3: The Detail page
Here are the Struts actions used to navigate among the
two screens:
Figure 4: Actions for the DVD application
The DVDs are held in an XML-file (dvds.xml) placed in
the application root directory. To read this file I've used JDOM. To better understand
the following examples you should know that the list
action instantiates a module called DVDManager which
reads this xml file and stores it as a JDOM structure in session
scope. The other actions may then fetch DVD information through
simple calls to the DVDManager
The application is
started with the list action. On a Tomcat server you'd
enter this address in your browser:
http://localhost:8080/dvdlib/list.do
Installing the DVD application and STC
To run the application and the STC programs you need these
components:
- The DVD Library application
- Struts 1.1
- STC
- JUnit
- JDOM
To ease the process of getting these components I've packed
them all as a war-file. Place it in
your servlet container, start the container, and the application
is running. NOTE: the size of the file is 1.2 MB.
If you
already have Struts 1.1, and maybe some of the other components
as well, you may download this zip-file
containing only the application-specific files (jsp, web.xml,
struts-config, application class-files etc.). The size is only
26 KB.
If you need to download some of the other components use these
