  2. What is Roo? • Productivity tool • Allows for easy creation of Enterprise Java applications • Runs alongside existing projects • Detects changes made to files, adjusts itself as necessary

  3. What Roo is not. • Roo is not a runtime • Roo is not an IDE plugin •  Roo is not an annotation processing library • Java EE 6 annotations are not used • Compatible with Java EE 5

  4. Core Technologies • Spring Framework • AspectJ

  5. Spring • Spring Framework is required by Roo • Spring Aspects - using AspectJ definition language • Configurable dependency injection • Other Spring projects may be included • Spring Security • Spring Web Flow • Maven • Java Server Pages • User decides which Spring components to integrate

  6. AspectJ • Aspect Oriented Programming (AOP) framework • Inter-Type Declaration (ITD) • Automatic Code Generation • Interfaces • Methods • Fields

  7. Why use Roo? • Higher Productivity • Compatibility with existing projects • Auto-configuration available: • Java Persistence API (JPA) • Database backend • Dependency injection • Integration with existing technolgies • Spring MVC layer • Google Web Toolkit • HTML 5 standard

  8. Productivity • Code generated in separate files • Independent from project • ITDs are referenced automatically • Incremental approach to application-building • Technologies and frameworks automatically added on-demand

  9. Compatibility • Compatible with Java EE 5 • SpringSource certified architecture • Automatic maintenance and updates of XML, JSP files

  10. Convenience • Runs in background • Simple command-line interface • Easy to add or remove • Fail-safe, keeps track of changes made to filesystem
