    blueMarine photographic workflow with Java blueMarine photographic workflow with Java Presentation Transcript

    • blueMarine photographic workflow with Java or Why You Should Really Ship Swing Applications Fabrizio Giudici Senior Java Architect
    • Overall Presentation Goal Talk about issues with Java Rich Client Applications A real project perspective Enumerate and introduce solutions www.javapolis.com
    • Speaker’s Qualifications  Senior Java Architect with 12 years of Java experience  Project leading, mentoring, teaching  Member of JUG Milano, NetBeans Dream Team  Speaker at JavaPolis, Jazoon, JavaOne, Jini Meeting  Writer for NetBeans Magazine, Mokabyte  Blogger at Java.Net www.javapolis.com
    • Java is mature for Rich Desktop Applications. Just look beyond Swing. www.javapolis.com
    • Java is mature for Rich Desktop Applications. Just look beyond Swing. (beyond - not in another direction) www.javapolis.com
    • The blueMarine project  Whole photographic workflow  Be creative with technology  Be open - more than some scripting APIs  FLOSS is not (only) a matter of freedom...  ... but of better stuff  Do special things for special communities  e.g. amateur astrophotographers, birdwatchers, ...  It all started in 2003 www.javapolis.com
    • DEMO Splash
    • Java for Desktop Readiness Phases  Phase -1: prior 2005  Slow, poorly integrated, ugly L&F  Phase 0: 2005  JDK 5 spreads, “Extreme GUI Makeover” starts  Phase +1: 2006-2007  JDK 6, Aerith, SwingLabs matures  TimingFramework, Nimbus, Filthy Rich Clients  Phase +2: 2008  Add NetBeans RCP: Filthy Rich Platform Clients  Ready for complex applications - anyone? www.javapolis.com
    • Java for Desktop Readiness Phases   blueMarine Phase -1: prior 2005 Slow, poorly integrated, ugly L&F 0.8  Phase 0: 2005 died here  JDK 5 spreads, “Extreme GUI Makeover” starts  Phase +1: 2006-2007  JDK 6, Aerith, SwingLabs matures  TimingFramework, Nimbus, Filthy Rich Clients  Phase +2: 2008  Add NetBeans RCP: Filthy Rich Platform Clients  Ready for complex applications - anyone? www.javapolis.com
    • Java for Desktop Readiness Phases   blueMarine Phase -1: prior 2005 Slow, poorly integrated, ugly L&F 0.8  Phase 0: 2005 died here  JDK 5 spreads, “Extreme GUI Makeover” starts  Phase +1: 2006-2007  JDK 6, Aerith, Swing blueMarine 0.9  TimingFramework, Nimbus, Filthy Rich Clients  Phase +2: 2008 reborn here  Add NetBeans RCP: Filthy Rich Platform Clients  Ready for complex applications - anyone? www.javapolis.com
    • Problems www.javapolis.com
    • Solutions www.javapolis.com
    • If you can just remember four points...  NetBeans RCP  NetBeans Visual Library  SwingLabs  NASA World Wind for Java www.javapolis.com
    • OpenBlueSky  Where generic stuff spins off blueMarine  Can be used for other applications  Consolidated stuff will be submitted for standard APIs enhancement www.javapolis.com
    • References  weblogs.java.net/blog/fabriziogiudici  bluemarine.tidalwave.it  openbluesky.dev.java.net  mistral.tidalwave.it  forceten.tidalwave.it www.javapolis.com
    • References  www.netbeans.org/features/platform  www.netbeans.org/community/magazine  graph.netbeans.org  www.swinglabs.org  timingframework.dev.java.net  worldwind.arc.nasa.gov/java  quaqua.dev.java.net  nimbus.dev.java.net  personales.ya.com/nimrod www.javapolis.com
    • NetBeans RCP www.javapolis.com
    • Question What do you expect from a (desktop) framework? www.javapolis.com
    • Desktop frameworks  Solid foundation to base your application  APIs working together, well tested  Service discovery and provider  Plugin support  Messaging infrastructure (via events)  Integrated help system  And more 20
    • Swing is not a framework  Missing sophisticated components  date picker, tree+table, etc...  Neither service discovery nor providers  No plugins  No messaging (only simple listeners)  Threading issues  JSR-296 (Swing Application Framework) not good for large applications 21
    • What is NetBeans RCP? NetBeans { NetBeans IDE NetBeans RCP 22
    • What is NetBeans RCP? NetBeans { NetBeans IDE NetBeans RCP 23
    • What is NetBeans RCP? NetBeans { NetBeans IDE NetBeans RCP Your Desktop Application 24
    • NetBeans RCP  You start with a skeleton application  You populate it  panels, views  actions, menus, toolbars  etc..  Often declaratively  Based on Swing  You can integrate third parties' components  You can control the Look&Feel 25
    • Most important NetBeans RCP APIs  Actions  Modules  DataObjects  Nodes  Dialogs  Options  Explorer  Progress  FileSystem  Visual Library  Lookup  Windowing/docking 26
    • DEMO Explorers, Viewers, Actions
    • Lookup  Plays a fundamental role in many APIs  Repository for a bag of objects  Locator for services  Service service = Lookup.getDefault().lookup(Service.class);  Fires events  “Global” lookup can be used as a simple “event bus” 28
    • DataObject represents a file-based entity 29
    • You can extend DataObject 30
    • Lookup holds “capabilities” 31
    • A Node “represents” a DataObject 32
    • A Node has “capabilities” too 33
    • Representing set of selected (etc) Nodes 34
    • A View renders Nodes 35
    • An Action can be automatically enabled 36
    • Some points  You don't need to always use everything  E.g. just Nodes, no DataObjects  Can use them “incrementally”  NetBeans RCP keeps objects in sync  E.g. updating a DataObject → bound Nodes  E.g. Nodes bound to the same DataObject 37
    • NetBeans RCP stuff can be extended  What about a “cover flow” view?  Use JOGL for fast 3D  Just extend and create a new View  TimingFramework for animating stuff 38
    • DEMO CoverFlowView
    • Update Centers  NetBeans components (.nbm)  can be added / removed on the fly  can declare dependencies  can be versioned  can add actions, menus, toolbars  Pretty good for plugins  (See demo in a few minutes) 40
    • NetBeans Visual Library www.javapolis.com
    • NetBeans Visual Library  Support for graph- add screenshot oriented modeling from UML or MIDP designer  Nodes  Arcs  Routing  Interaction  Can be creatively used  Whiteboard paradigm  Use interactivity: touch, drag, change objects  PS Can be used with plain Swing apps 42
    • DEMO LightTable
    • GeoSpatial Components www.javapolis.com
    • JXMapViewer  A generic 2D, tile-based map renderer  See Joshua Marinacci's blog  Retrieves tiles from the web (or locally)  Part of Swing-WS (SwingLabs)  Can stick objects to the map  Hint: integrate it with the Visual Library www.javapolis.com
    • DEMO GeoViewer
    • NASA World Wind for Java  Java version of NASA World Wind  3D software that renders the Earth  NASA terrain imagery  Other data sets can be plugged in  if legal stuff is ok...  Based on JOGL 47
    • DEMO GeoViewer 3D
    • Java Imaging APIs www.javapolis.com
    • Java Imaging APIs  Many options (and dispersive?)  Java2D, JAI, ImageJ, JMagick, JHLabs, ...  Some too difficult  Wild behaviour and performance differences  Parallel Computing is a must  Multi Core  Small, local mini-grids  Massive Grid Computing  There's not a global community www.javapolis.com
    • Mistral: fix 'em up  Imaging meta-framework  Multiple APIs can be used together  Simplifies APIs  Supports multicore, Jini, Sun Grid www.javapolis.com
    • Open Problems for blueMarine  Java still misses something on the desktop  e.g. video streaming, USB support  Can be worked around with JNI/JNA  Java 7 is not too far  Some NB RCP stuff not fully customizable  Better integration NB RCP SwingLabs  Compliance to Apple HIG  Linux + JOGL issues  No JAI native support for Mac OS X 52
    • A final point www.javapolis.com
    • Be efficient with innovation  “Cool stuff„ often means complexity  Go quickly from idea to prototype  Integrate easily others' stuff  NIH isn't a killer-idea, but an idea-killer  Build cool demonstrators  ... and cool applications soon after  (stay tuned for some new cool stuff) 54
