The Big DealDesktop or not Desktop?

The Big Deal [What?]

We want a Desktop client!!

OK, let’s use both Desktop and Web Clients

The Big Deal [2006] [Why?]

↓↓ Few Plugins

↓ Inmature

↓↓↓ Hard To Learn

↓↓↓↓ Unreal

↓↓↓↓↓ Privative

↓↓↓↓↓↓ Heterogeneus

The Big Deal [The Winner]• Why Spring RCP?• Provide a way to build

structured, highly-configurable, GUI-standards-following Swing applications faster by leveraging the Spring Framework

• Foster integration with existing rich-client-related projects where it make sense. For example, jgoodies-forms and TableLayout are two good layout managers. We don't need to develop another one.

• Adhere to the principles set forth by the Spring Framework programming to interfaces; the importance of sound OO design, documentation, and testing.

PrototypingHow looks like?

How ToThe key concepts of our child

How To [Key Spring RCP Features]• Almost everything are beans• Swing programming without knowing Swing• Command ‘framework’• Form data binding• Based on Eclipse concepts (Perspective, view)• I18n, validation, support classes, icon and image

abstraction…• Out of the box integrations:

– JGoodies– Acegi/Spring Security– Hibernate Validator– …

http://netbeans.dzone.com/news/spring-rcp-tutorial

How To [Bluebell Improvements]1. Easier configuration (CoC)2. Module based approach3. Out of the box scaffolding and new commands4. Non intrusive: prefers ‘extensions’ and ‘aspects’

over ‘patches’ – Enable to migrate from current installations!!

5. Modern look’n feel6. Bug fixes and utility classes7. Testing ‘framework’8. Spring 3 and Maven 39. Integrations10. Multiple deployment models11. Performance improvements

How To [1. Easier Config. - CoC]• Maven artifacts• Main class

org.bluebell.richclient.application.RcpMain

• Separation of concerns (application contexts)– Startup: Defines the splash screen, but could define anything that

you want to have happen specifically at startup

– Richclient: Configures the Spring RCPcomponents and services.

– Command: Provides the application's commands, organized within menu bars and toolbars, and the items within them

• Shared Beans
