Demo # 1 – A Simple Web Application

11. Features Covered Project management Persistence Entity support
Field Management
JUnit testing
Spring MVC Controllers, Selenium testing
Logging

12. Under the Hood
Implementation Overview
Code Generation

13. Implementation Overview

14. Code Generation Approach
Passive Generation
Active Generation
Roo is a Hybrid code generation

15. Active Generation

16. Demo # 2 Let’s Secure the app

17. Demo # 3 Speaker should get an Email

18. Demo # 4 Application speak Dutch

19. Demo # 5 How social is your app?

22. # Demo 7 – Moving to Cloud Changes to make
persistence setup (Google App Engine)
gwt set up
add aspects for key generation
Remove constraints (unique)
do mvn gwt:compile gae:deploy

23. Issues on Google App Engine
Spring MVC app does not work
Relationships do not work
Integration tests do not work (ROO-1711)
Constraints do not work
Enum does not work

24. Removing Roo from app Use AJDT's "push-in refactoring" feature
This moves the Roo .aj content into normal .java files
annotations from .java files
Regular expression (\n.*Roo.*\n) find/replace in eclipse
Remove Roo's annotation JAR from your POM
dependency remove command

25. Features Not Covered JMS support JSON support SOLR support (Search)
Spring Web Flow
Add-on creation

26. Future Sneak Peak Spring Integration support
Better Google App Engine support
