2. © 2006 IBM Corporation Agile Planning’s JavaScript Experience  > 3 years of experience with JavaScript and Dojo  Used WTP (JSDT), Aptana, Dashcode, Text Editors  Writing JavaScript code is easy...  …evolving and refactoring a large codebase is not  requires disciplined programming  requires well organized and talented team  hard for new team members to get started

3. © 2006 IBM Corporation Ways to Improve - Requirements  Need a growth-path from existing code  No lock-in  Must fit in existing infrastructure  Do not introduce new layers / indirections  Should leverage existing tooling

4. © 2006 IBM Corporation Ways to Improve - Options  Tooling for (Dojo flavored) JavaScript  Translate from another language –GWT –Eclipse E4 –JavaScript++

5. © 2006 IBM Corporation Introducing JDojo  JDojo provides a pragmatic solution  JDojo is an JDT Compiler Participant  Doesn’t bring Java to JavaScript, but JavaScript to the Java tooling  No new layers: –Use dojo as the widget toolkit –Allow working with the DOM

6. © 2006 IBM Corporation Demo

7. © 2006 IBM Corporation JDojo Features Type Safety, Generics, Function Objects, Inheritance, Interfaces, Arrays, Code Inlining, Variable Arguments, (Checked) Exceptions, Assertions, Enumerations, Method Overloading, Inner Classes, Object Initializers, Reflection, ECMAScript API, DOM API, Dojo API, Jazz Foundation API, Correct dojo.require’s, compile upon save, Jazz WebUI Foundation compatible …

8. © 2006 IBM Corporation Outroducing JDojo  Takes full advantage of JDT Tooling  Interest in generated JavaScript code only  Generated JavaScript code is readable  Debugging can be done using existing tools  Interoperable with existing JavaScript code  No overhead in generated JavaScript code

9. © 2006 IBM Corporation JDojo Benefits  Compiler helps finding API breakages  More consistent JavaScript code  Allows components to specify API  Document API using JavaDoc, @Deprecated,...  Tooling opportunities

10. © 2006 IBM Corporation Java based JavaScript Runtime  Developed for RTC 2.0  Improved for optimal interoperability with JDojo  Allows sharing code between Web and Eclipse

15. © 2006 IBM Corporation Use Case: Tempo Simulation

16. © 2006 IBM Corporation Why a ScriptEngine?  Rhino exposes low level interfaces  Rhino exposes Java objects using LiveConnect  Allow to move the Java / JavaScript boundary  Usage by define an Eclipse Extension

17. © 2006 IBM Corporation ScriptEngine Features  Initialize Dojo Runtime  Script loading infrastructure  Java types are exported as Dojo types  Transparent wrapping of Java / Script Object  Supports debugging using Eclipse E4 debugger  Future: Web Environment for WebUI Testing

18. © 2006 IBM Corporation Conclusion  JDojo and ScriptEngine are independent tools…  … yet are a perfect marriage  Proven to work in RTC releases  Enabler to build what APT is today in a short timeframe  Allows us to provide an unified API

19. © 2006 IBM Corporation Future Development  Zurich Team –writes new code with JDojo –Uses ScriptEngine in APT and Work Item –Provides stubs for other components as Bundle Fragments as long as they did not yet adopt  Looking for other Teams (you?) to participate
