2007 JavaOneSM Conference | Session TS-3160 | 31 Solution: Quickstarter ● Pre-load the cache, before launch ● At boot, at browser launch, whenever ● Note: Not the same as having a running VM ● Cooperates with the OS ● Memory still available for other apps ● OS will flush disk cache pages as necessary 2007 JavaOneSM Conference | Session TS-3160 | 32 Problem: Install Time ● The JRE implementation is, well, big ● 7–15 MB download ● Extracted to 40+ MB for rt.jar ● Plus other jarfiles, native libraries, resource files, … ● All of this takes time ● Download ● Unzip ● Unpack200 ● Copying bits around ● It’s a wonder that it’s as quick as it is… 2007 JavaOneSM Conference | Session TS-3160 | 33 Solution: Kernel ● Every app needs some core functionality ● VM, networking, security, classloader ● …plus other stuff on demand ● Swing, AWT, 2D, CORBA ● Kernel downloads and installs ● Bare essentials immediately ● Additional dependencies next ● “ClassNotFound” culprits as needed ● Everything else eventually 2007 JavaOneSM Conference | Session TS-3160 | 34 Kernel: Bare Essentials 367KB4.3 Core JRE Web Start 9.1 197KB Plug-in Installer 1374KB 3.1 82KB 2.4 2007 JavaOneSM Conference | Session TS-3160 | 35 Kernel: App-Specific Sizes 2007 JavaOneSM Conference | Session TS-3160 | 36 Problem: JRE Software Detection ● No good way to detect JRE software existence and version from browser ● Developers use nifty “Get Java” button ● Which takes users away from the site ● Applets constrained to lowest-common- denominator APIs ™ ● MS VM, circa Java Development Kit (JDK ) 1.1 2007 JavaOneSM Conference | Session TS-3160 | 37 Solution: Deployment Toolkit ™ ● JavaScript technology solution hosted by Sun ● Developer uses simple script on their site ● Link to Sun’s script ● Detects JRE software existence and version ● Depending on app requirements
