The dragonslayers wrote the most recent version of their Go-ForIt application using Struts and used the Data Access Object pattern to experiment with different technologies for persisting application data with minimal impact on the application code. This tutorial is based on their experiences developing Java Data Objects (JDO) that are persisted in DB2 Express using WebSphere Studio Application Developer and TJDO, an open source implementation of theJDO Speciification.
This tutorial assumes you have some familiarity with Web application development using Java and with interacting with relational databases using JDBC. Knowledge of DB2 or WebSphere Studio Application Developer (Application Developer) is helpful but is not required.
System requirements
To follow along with the tutorial, you'll need the following software:
WebSphere Studio Application Developer Version 5.0. You can download a trial version here.
DB2 Universal Database Express Edition V8.1. You can download a trial version here.
