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

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

Ways to Improve - Options
Tooling for (Dojo flavored) JavaScript
Translate from another language
– GWT
– Eclipse E4
– JavaScript++

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

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

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

Java based JavaScript Runtime
Developed for RTC 2.0
Improved for optimal interoperability with JDojo
Allows sharing code between Web and Eclipse

Use Case: Tempo Simulation

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
© 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

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

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
