Wire EMF Databinding RCP

THIS IS AN ARTICLE WORK IN PROGRESS (Bug 195163)

Abstract/Requirements Definition

I'm trying to implement a fairly simple address book application on top of RCP using frameworks provided by Eclipse in 3.3. There's also focus on how to structure and design an RCP to be as extensible and as flexible as possible, including theming, internationalization, datastorage independency, ... .

Setup the Toolchain

1. Eclipse 3.3 for RCP-Developers (available from http://www.eclipse.org/downloads)
2. EMF using the Update-Manager (Help>Software Updates>Find and Install)
3. Derby-Plugins (available from http://db.apache.org/derby/derby_downloads.html)
   To install:
   1. Stop your eclipse (if running)
   2. Unzip „derby.zip“s (as of this writing derby_core_plugin_10.2.2.485682.zip and derby_ui_plugin_1.1.0.zip) into your %ECLIPSE_HOME/plugin directory
   3. Start up eclipse
4. iBatis (available from http://ibatis.apache.org)
5. Fetch application icons (e.g. available from http://websvn.kde.org/trunk/KDE/kdelibs/pics/oxygen/ using your favorite SVN-Client)
6. (Optional) Visual-Database Design
   1. Install Clay for Eclipse (available from http://www.azzurri.jp/en/software/clay/)
   2. Download Clay-Utils used for creation of DDL and documentation (available from http://publicsvn.bestsolution.at/repos/java/clayUtils/release/at.bestsolution.clayutils-nodeps-0.0.7.jar)
   3. DDL-Utils to create database DDL for any database you want (available from http://db.apache.org/ddlutils)
7. (Optional) Subclipse for Version-Control (available from http://subclipse.tigris.org)

Application Design

Plugin-Design

at.bestsolution.addressbook

The main RCP-Application

at.bestsolution.addressbook.ui

This plugin provides the UI bits (ViewPart, ...) for the addressbook application.

at.bestsolution.addressbook.ui.theme

This plugin addresses the themeability of the application by providing a plugable theme-API. It will by default provide a standard theme.

at.bestsolution.addressbook.core

This plugin provides the none GUI bits for the application like Command-Definitions, handlers, ...

at.bestsolution.addressbook.core.model

This plugin provides the model implementation created using EMF

at.bestsolution.addressbook.core.datasource

This plugin will provide the API to provide plugable datasources in our case

at.bestsolution.addressbook.core.datasource.xmi

This plugin provides a datasource implementation on top of XMI (directly supported by EMF)

at.bestsolution.addressbook.core.datasource.iBatis

This plugin provides a datasource implementation on top of iBatis

Plugin Overview

Domain Model

The domain model is fairly simple and can be represented by 2 classes as shown in the diagram below. The only interesting thing is that there's a bidirectional relationship between Person(Attribute: primaryAddress) and Address(Attribute: person).
