3 3 Agenda Introducing Roo Demo for Unbelievers Under the Hood Capability areas (lots of demo) Cloud Support Removing Roo Conclusion and Q&A

4 4 Springs Mission #J2EE or JavaEE should be easier to use

5 5 Mission Accomplished ! Now What?

6 6 Spring Roo Development Tool

7 7 Spring Roo Mission Roo's mission is to fundamentally and sustainably improve Java developer productivity without compromising engineering integrity or flexibility

8 8 What is Roo? Rapid Development Tool for Spring Development time only No Runtime No Negative Performance Impact No Memory Overhead No Roo Deployment Uses Best of Breed Spring 3, Spring Security, Spring MVC / Web Flow Junit, Log4J, Maven, AspectJ, Eclipse

9 9 Why should we use Roo? Easy Configuration Great Learning Tool Spring Best Practices Restful Web Services, JPA persistence, Security, Integration tests, Selenium test cases, JMS Standards Bean validation, Dependency Injection Powerful Features GWT, SOLR, DBRE, NoSQL, Spring Integration (coming soon)

10 10 Demo for Unbelievers Demo # 1 – A Simple Web Application

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

12 12 Under the Hood Implementation Overview Code Generation

13 13 Implementation Overview

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

15 15 Active Generation

16 16 Demo # 2 Lets Secure the app

17 17 Demo # 3 Speaker should get an

18 18 Demo # 4 Application speak Dutch

19 19 Demo # 5 How social is your app?

24 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
