    Reengineering the interface

    Objective: Interface upgrade to present standards

    Approach: Migrate 1999 interface to 2007 state-of-the-art GUI

    Weakness: Obsolete Client Architecture (thousands JSP files)

    Strength: The 1999 Server Architecture (POJOs + OODB)is still state-of-the-art

  • Selecting a framework / technology

    Many goo solutions

    Own framework ? Cost of supporting what others might doing well ?

    Ajax vs Flash ? OpenLazslo, Adobe Flex Flash plugin dependency ?

    Ultra lightweight client + server-side Java ? echo2, zk, ... Do they scale well ?

    Existing JS frameworks ? Dojo, Scriptaculous/Prototype, ... JavaScript language ?

    The JavaScript nightmare Fun but language is too flexible (global vars,...) Requires an extremely strict discipline (convention) for a team How to handle efficiently tens of Klocs ? Browsers quirks




  • Google Web Toolkit (GWT) ?

    What is GWT GWT is a Google framework for building AJAX apps in the Java language Open Source Apache 2 Licence Java --> JavaScript translation

    'Industrial' software engineering Tools ! Tools! (IDE Eclipse & GWT hosted mode + svn integration perfect for teams) Standard Java refactoring, debugging, testing, source code manipulation Compile time vs Run time errors detection

    Advantages Performances:

    Aggressive caching, code optimization, compression Clean backend integration:

    Efficient Java RPC mechanism Portability:

    Generates platform-specific code Native JavaScript is still reachable:

    JSNI (JavaScript Native Interface) Developer Community:

    Large (Forums : 6900 users, 250 contributors) and active (+20K posts)

    But... Java knowledge required for UI designers CSS only is not realistic





  • CO enhancements to GWT

    MV(C) framework Strict model/view separation Necessary for even driven interfaces (AJAX is asynchronous) Side effect : ease collaboration between presentation

    and business logic developers
