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

Spring’s Mission #J2EE or JavaEE should be easier to use

Mission Accomplished ! Now What?

Spring Roo Development Tool

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

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

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)

Demo for Unbelievers Demo # 1 – A Simple Web Application

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

Under the Hood Implementation Overview Code Generation

Implementation Overview

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

Active Generation

Demo # 2 Let’s Secure the app

Demo # 3 Speaker should get an Email

Demo # 4 Application speak Dutch

Demo # 5 How social is your app?

Demo # 6 Have an Existing Database

Cloud Support

# 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

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

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

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

Future Sneak Peak Spring Integration support Better Google App Engine support More view technologies support NoSQL support Ne04j

Conclusion and Q & A Roo delivers serious productivity gains for Java Popular, mature libraries you already know Easy to learn and use No runtime, no lock-in, no risk ITDs separate clearly generated from non- generated code Questions?
