Getting Started
Import CS496_Lab14.zip into Eclipse (Import → General → Existing Projects into Workspace → Archive File).
You should see a project called CS496_Lab14.
Update: Derby version
Here is a slightly modified version that uses Apache Derby rather than SQLite:
It depends on the following Eclipse project (which contains the Derby jar files):
Derby is a better choice than SQLite for server applications where multiple clients will be making requests concurrently.
Real Persistence
The project you imported is a combination of Assignment 1 and Assignment 4. Specifically, it is both a web service and a web application. ("It's a floor wax and a dessert topping.")
The only difference between the lab and the assignments it is based on is that it has a new implementation of the IDatabase interface called SqliteDatabase, which (as specified in the Database class) is the implementation that will be used when the program runs.
Note that the Derby version uses a DatabaseProvider class, where the IDatabase instance is set by a DatabaseInitListener configured in the
web.xmlfile. This approach is more flexible than the one used in the original version of the lab.
Start by executing SqliteDatabase as a Java application (or DerbyDatabase if you are using the Derby version). You should see the following output:
Creating tables...
Loading initial data...
Done!
Refresh the Eclipse project. You should see a file called test.db. This is the database! It allows the inventory data to persist between runs of the application.
Now, run the Main class as a Java application. Navigate to
to see the UI for the web application. Note that adding items is supported — try it out!
Your Task
Add support to the web application for editing items and deleting items.
Add support to the web service for the various REST operations. Note that the URL for the web service will be
You should be able to reuse your controller, servlet, and JSP code from the assignments.
