This document discusses using Flex and Grails together for building Rich Internet Applications (RIAs). It covers: 1) Why use Flex - for better user experience without browser compatibility issues and clear client-server separation. 2) Why use Grails - as a Rapid Application Development (RAD) framework that is Java-based with conventions over configuration. 3) A sample application demonstrating creating a Grails project, installing plugins, generating domain classes, modifying configuration files, and starting the server to access the Flex UI.

3. Flex for RIA Why RIA? Better User experience No Browser Compatibility Issues Client-server architecture with clear separation of concerns Why Flex? Mature Better penetration

4. Grails as RAD Why RAD? Scaffolding Convention over Configuration Why Grails? Java based

5. Architecture – TODO improve

6. Sample App - teps Grails Project Creation Plugin installation Generating domain class model Edit generated domain classes Modify config files to enable security Generate Flex code Start server and navigate

7. Scaffolding Grails Project Creation grails create-app gsf-test Plugin installation cd gfs-test grails install-plugin flex-scaffold grails stark-security-install-full

8. Sample app – domain model

9. Generating domain class model grails create-domain-class customer grails create-domain-class company grails create-domain-class phone grails create-domain-class address Sample app – domain model

10. Edit generated domain classes Company Customer Address Phone Sample app – domain model

11. Add to Config.groovy gfs.security = true Edit StarkSecurityConfig.groovy '/': Role.ALL_ROLES, to '/**': Role.ALL_ROLES, Edit BootStrap.groovy Sample app – domain model

12. CRUD Generation grails generate-all-flex company grails generate-all-flex customer Flex compilation grails flex-tasks Start app-server grails run-app go to http://localhost:8080/gfs-test Sample app – domain model

13. Does it really work? Learning curve for Flex, Grails (Groovy, GORM), Generated code – Flex Understand, Maintain Scaffolding plug-in Separate frontend, backend teams Costs – Flash Builder license

14. Front end Design Design of Generated frontend code

15. Connectivity Options BlazeDS – Flex Plugin GraniteDS - GraniteDS Plugin Webservices (REST, SOAP) - CXF Plugin

16. Security options Spring Security Apache Shiro

17. Deployment Options Desktop : Adobe Air Gaelyk app on Google App Engine Grails app on Google App Engine Grails War on standalone container

18. IDE Flash Builder Springsource plugin for Grails

19. Thanks!
