Basically…
 We need an architecture that supports distributed development over a large
number of autonomous development groups
 We need a component concept where components are loosely coupled and
can be started (and stopped) independently
 We need a way to describe external interfaces of components and
dependencies between components
 We need a way to only start the components as they are needed – also
known as late activation
 We need all this to work over multiple generations of components

Eclipse Architecture
 Goals for the Eclipse architecture
 Be able to host any number of 3rd
party applications
 Scalability in terms of size and complexity of hosted applications
 Alignment with native UI look-n-feel
 Flexible architecture, structured around
 Plug-ins – the basic unit of functionality
 Extension points – the defined interfaces between plug-ins
 This architecture allows for
 Implementation of 3rd
party applications on top of the basic platform
(Eclipse RCP)
 Additional tools to be integrated in the platform
 Integrated tools to be further extended

The Basic RCP Components
 In the Eclipse, everything is a plug-in including the run-time platform itself
 It is a small kernel that represents the base of the platform
 Built on top of OSGi
 All subsystems built on the run-time platform follows the rules of plug-ins:
 They are plug-ins themselves
 RCP includes:
 Component Management
 Resources Management
 Preferences
 Workbench (include SWT and JFace)
 RCP does not include functionality that are not commonly needed:
 Update
 Help
 This can be included from the Eclipse platform

Organizing the Platform
 The software of an Eclipse system is based on the following terms:
 Plug-ins – a plug-in is the basic unit of software
 Fragments – a fragment is an add-on to an existing plug-in with
additional functionality
 Features – a feature is a number of plug-ins that is distributed and
updated as a whole
 Applications – an application is a Java class that implements a specific
interface and is declared as such in the plug-in
 Products – a product is a set of features or plug-ins along with the
appropriate branding

Extension Points
 Describe additional functionality that could be integrated with the platform
 External tools extend the platform to bring specific functionality
 Java Development Tooling (JDT) and Plug-in Development Environment (PDE)
are external tools integrated with the platform
 Extension points are used to
 Add an implementation for a generic feature
 Extend the workbench
 Extend common object factory
 Advantages:
 Allows for late load and startup of plug-ins
 Provides a common “registry” for most extensions like views, perspectives,
commands, etc
 Disadvantages:
 Makes it harder to understand flow of control
 ID Hell!
 Extension points may have corresponding API interface
 Describes what should be provided in the extension

Choosing Eclipse RCP
 Business Requirements
 IT/Project Requirements
 The Basic Architecture
 The Process

27. PR0017 - 2009-09-29
27
Business Requirements
 Provide process support
 Show/hold all functionality and information in one place
 Seamlessly integration between the functional areas
 Data re-use
 Integration Support
 Integration with existing applications such as 3270, browser based and
native Windows (word, excel etc.)
 External peripherals
 High usability
 Follow the OS
 Standard keyboard navigation, icon, help, drag & drop
 High performance

28. PR0017 - 2009-09-29
28
IT/Project Requirements
 Parallel development
 No hard decencies to the other projects
 Different release dates for the a functional area (projects)
 Different dependencies to the back-end
 Nordea is a bank, - not a major IT product company
 Mature and well tested framework
 Go out and buy the funtionality

The Process
 Project started in 2006 with an evaluation
 Several different frameworks were evaluated

Portal based

Eclipse RCP

NetBeans Platform
 Several Eclipse RCP frameworks were evaluated
 Major part of the evaluation was a fully functional prototype
 Access to ”real” data
 Divided into functional areas as a number of independent plug-ins
