How Much Java Technology Is Out There? • >91% of all PCs run Java platform* • ~77% of all Java technology-enabled PCs run Sun’s Java Platform, Standard Edition (Java SE platform)** • Distribution through PC OEMs > Nine of the top ten PC OEMs ship the Sun JRE software > Representing >60% of all shipped PCs > 58 white box vendors have signed JRE software redistribution agreements

• Download/installs > ~44m installations / month for the last six months on Windows > >50M in Jan, Feb, April, 2007 * Omniture, April 2007 **Mapsolute/Map24.com, April 2007

Problems to fix • • • •

Startup Time Install Time JRE Detection Applet support

12

Quickstarter • “Coldstart” vs. “Warmstart” • Root problem: > Large files + Disk access speed

• Solution: QuickStarter > Pre-warm the disk cache

• Note: QuickStarter != running VM > Smaller footprint, more targeted disk pages

Startup Time Install Time JRE Detection Applet support

14

Install Time • Java's not small > J2SE 5.0: 7.1 MB > Java SE 6: 10+ MB > rt.jar: 40+ MB on disk

• Lots of bits being moved around > Download, Unzip, Unpack200, Copying

• Solution: Java Kernel > Download only core dependencies first > Launch application > Download and install in the background 15

Look Mom! We Shrunk the JRE

Startup Time Install Time JRE Detection Applet support

17

Deployment Toolkit • Detecting Java from a web page is hard > Does the user have Java? > What version? > How to get user to install and return?

• Result: Most applets use old (1.1) APIs > Allows them to run compatibly on old versions > e.g., MS VM

• Solution: Deployment Toolkit > JavaScript hosted at Sun for general detection > Plugins (ActiveX and Mozilla) for more specific detection > Detect, start installation if necessary, launch

18

Detecting JREs <script src="http://java.com/js/deployJava.js">

Detected JREs: <script> jres = deployJava.getJREs(); document.writeln(jres.length ? jres : "None");

Advantages

• Improved reliability • Improved user experience > Applets launch in the background

• Built-in JNLP support • Per-applet command line arguments > Heap size, Java 2D acceleration options, ...

• Improved Java/JavaScript integration • Improved Windows Vista support > Signed applets now work correctly in Protected Mode

Internet Explorer

25

Applets Reloaded • Ground-up rewrite of the Java Plug-In > Mostly in Java

• Advanced new architecture > Out-of-process execution

• Major benefits > > > > >

Improved reliability Support for larger Java heap sizes for applets Better support for signed applets on Windows Vista Support for per-applet JVM command-line arguments Support for multiple simultaneous JRE versions 26

Compatibility • Better than 97% backward compatibility > Based on runs of hundreds of applets from throughout

the web > Continuing to improve

• Applet lifecycle unchanged > init(), start(), stop(), destroy()

• All services supported: Browser proxy settings Browser certificate store Browser authenticator Browser cookie store showDocument() support Modality handling Java/JavaScript integrationPrinting

27

JNLP Support • Most significant new feature • Unifies deployment between Java Web Start and the Java Plug-In > Simply choose the top-level container (Frame / Applet)

• Incorporate JNLP extensions trivially in applets > JavaFX run-time libraries, JOGL, Java 3D, JAI

• Use JNLP APIs from applets > PersistenceService, DownloadService, ...

• Full support for JVM command-line arguments, JRE version selection, JRE auto-download 28

JNLP Support <param name=“jnlp_href” value= “my_applet.jnlp”> <jnlp> <j2se version=”1.4+” max-heap-size=”128m” /> <property name="sun.java2d.noddraw" value="true"/> <jar href=“my_applet.jar” main=“true”/> <extension name= “jogl” href=“...”> 29

Java / JavaScript Support • Completely rewritten Java / JavaScript integration • More complete, reliable and portable than before • Formerly Mozilla-specific functionality now working in Internet Explorer > Static method access > Construction of new Java objects from JavaScript

• Opportunity to respecify and reintroduce “LiveConnect” • Opportunity to change the nature of AJAX 30

JavaFX Content in Applets • JavaFX Script compiles down to Java classes • Trivially hosted in applets • Pull in JavaFX run-time libraries and dependent libraries (scene graph, video, 3D) via JNLP extensions > Identical to deployment in an application

• Higher-level abstractions accelerate GUI application development

31

Experimental Functionality • New Java Plug-In technology supports dragging applets out of the web browser as a deployment paradigm > Applets are mini applications that run anywhere > In and out of the browser • Highly experimental > Not guaranteed to be supported in this release or future releases > Functionality will very likely change > Please provide feedback on Java Plug-In forum on java.net

32

Experimental Functionality • Enable with new applet parameter <param name=”draggable” value=”true”> • By default, Alt + Left-click + Drag anywhere in the applet's region is the drag gesture • Can be customized by providing a method on your applet public boolean isAppletDragStarted(MouseEvent e);

33

Experimental Functionality • Applet is placed into a new top-level Frame > Frame is used for Applet subclasses > JFrame is used for JApplet subclasses • By default, the new frame is undecorated and opaque • Can change this, and perform other custom operations, at the time the drag is initiated by providing a method on your applet public void appletDragStarted();

• At the time this method is called, your applet is in the new top-level Frame, that Frame is undecorated, and it is not yet visible 34

Experimental Functionality • A separate “close button” separate from the Frame tracks the movement of the Frame around the screen if undecorated • Can customize this by providing a method on your applet public void setAppletCloseListener(ActionListener a);

• If you implement this method, you should draw some sort of close button in your applet's region • Call the ActionListener when the close button is clicked to initiate shutdown of your applet

35

Experimental Functionality • While the web page where the applet came from is still visible, the applet can still talk back to the browser > Java/JavaScript calls still allowed > Can still interact with the surrounding web page • Once the page is closed, reloaded, or navigated away from, the applet is disconnected from the browser • Services provided to the applet degrade gracefully > Java/JavaScript calls disallowed > AppletContext.showDocument() is implemented by opening a new browser window; target is ignored > ... • When applet is closed, normal applet teardown occurs > stop() and destroy() are called

36

New Plugin Architecture • Please test it and let us know! > https://jdk6.dev.java.net/6uNea.html

• Windows: > Java Control Panel, “Advanced” tab > “Java Plug-In” node > Select the checkbox: > “Enable the next-generation Java Plug-in”

• Linux/Solaris > Symlink to lib/{i386,sparc}/libnpjp2.so from firefox/plugins or

~/.mozilla/plugins directory > Remove any old symlinks to libjavaplugin_oji.so

37

But Wait, There’s More!

38

Graphics Goodies • Better Windows graphics performance > GPU-accelerated, using Direct3D > On by default

• Nimbus: > Cross-platform look & feel > More modern than current Metal look & feel > Opt-in: Not the default look & feel > Preserves backwards compatibility > Design tool for creating new skins
