One of the
EjbExamples,
FoodSmart is a free, open-source, example EJB application available from
GemStone Systems, Inc. It and an eval copy of the
GemStonej application server can be downloaded from
http://www.gemstone.com.
Here's the blurb from
FoodSmart's "about" page:
The FoodSmartTM iGrocer System
FoodSmart is a commercial grade, production quality e-commerce application, intended to show Java developers how to design Java 2 Enterprise Edition applications with the
GemStone/J application server.
FoodSmart is designed and coded by a development team with extensive experience in distributed systems.
The concept of
FoodSmart is a hypothetical business-to-customer e-commerce system for the retail grocery industry, in which
FoodSmart is a hypothetical grocery chain.
FoodSmart would help existing brick-and-mortar grocery chains deliver an increased level of service to their customers, by providing a website where the customers could draw on a database of recipes to create meal plans based on price, nutritional content, and other factors; and order delivery of the associated groceries. Future versions of
FoodSmart will offer facilities for tracking grocery orders through their workflow, including financial settlement, fulfillment, and delivery.
Technology Overview
FoodSmart is implemented with Java 2 Enterprise Edition technologies and is served by the
GemStone/J 3.2 application server.
FoodSmart uses Java Server Pages to dynamically generate its HTML and
JavaScript user interface. The business logic upon which the user interface depends is encapsulated by a set of Enterprise Java Beans and implemented in the Java 2 Standard Edition programming language. Internally, these Enterprise Java Beans use
GemStone/J's unique Persistent Cache Architecture and JDBC for persistence of objects and their data.
FoodSmart has some interesting features, like the ability to switch between object persistence and relational persistence, and the ability to switch between entity beans encapsulating its domain objects and no entity beans encapsulating its domain objects, based on properties read at start-up time.
GemStone Systems, Inc. intends to run an installation of
FoodSmart from its website in the near future.

Does anyone claim this is a good example of Java, Beans, OOP, etc? If so, what specifically are their claims (small code, fast, change-able, etc.) and how can they be tested? (
