  4. JavaOne Impressions • Last year “what we will do” • This year “what we did” • Lots of mature products with mature vendors • More reality and less hype

  5. JavaOne 1999 Cool Stuff • 10,000 PalmVs sold for $199 each to attendees. Pre-loaded with the K virtual machine (J2ME). • Real-time Java demo by IBM • Jini controlled Lego Mindstorm robots

  6. JavaOne 1999 Key Announcements • New “Java Editions” J2EE, J2SE, J2ME. • Roadmap for the next few releases of Java 2. • Java Community Process. • Misc.

  7. The Old View

  8. The New View

  9. Application Profiles • A way to add support for domain specific requirements. • Specifies exactly what support is provided to applications in terms of features, APIs, classes and (optionally) frameworks. • Test Suite

  10. Java 2 Enterprise Edition (J2EE) • Current JDK stuff : • CORBA, IIOP, Messaging, Transactions, RMI, JDBC, JNI, … • + EJB • + Servlets • + Java Server Pages • New Packaging and Deployment Ideas

  11. Java 2 Enterprise Edition Consists of: • J2EE Specification • J2EE Application Programming Model (best practices) • J2EE Reference Implementation • J2EE Compatibility Test Suite

  12. J2EE Concepts Components: EJB Containers: web, application • Web for JSP, Servlets • Application for EJBs • XML deployment descriptor idea extended to support JSP, Servlets, web content Connectors: for talking to legacy systems such as CICS and SAP

  13. J2EE Deployathon Demo • Showed the same used car eCommerce application EJB code running without *ANY* changes in: • Oracle App. Server • IBM WebSphere • Netscape NAS • BEA WebLogic • Gemstone J • and others

  14. Java 2 Standard Edition (J2SE) • What we all think of as the JDK • Targeted at desktop PCs and workstations • Next major release will include HotSpot • Netscape 5.0 will have J2SE built in via OJI and the Plug-in

  15. Java 2 Micro Edition (J2ME) • Targets high volume consumer devices • Highly optimized runtime with newly written JVM called K-Java • 40kb in size, with libs 128kb • suited for 16/32b RISC/CISC 16+ Mhz • written with Motorola, 3Com, Bull, Fujitsu • Palm V is reference platform • Psion has announced support

  16. Java 2 Roadmap “Cricket” Release (1.2.2) • due out July 1999 • bug fixes • Plug-in: • RSA signing • HTTPS support • silent install • 50% smaller download (5M) • fixed cookie support

  17. Java 2 Roadmap “Kestrel” Release (1.2.3) • due out Q1/2000 • http 1.1 • RMI over IIOP • 25% faster startup • 20% smaller footprint • GUI performance focus • HotSpot for client • Plug-in: • “sticky applets” and standard extensions

  18. Java 2 Roadmap Post “Kestrel” • Java 3 ??? Q1/2001 • new I/O API • Plug-in • support for multiple JVMs (not committed)

  19. Java Community Process • The way by which anyone can contribute to Java • 20 proposals underway • Audited by the independent auditing firm of Price-Waterhouse

  20. Java Community Process Java Specification Requests (JSR): • Orthogonal Persistence • J2EE Connector Architecture • Unified Printing API • Parameterized Types • See: http://java.sun.com/aboutjava/communityprocess

  21. HotSpot • Source will be available via SCSL • Built in to J2EE • Future releases promise an additional 40% performance improvement.

  22. Bill Joy Keynote • Quoted Arthur C. Clarke: “Any sufficiently advanced technology is indistinguishable from magic.” • Your phone should have common sense reasoning about context: e.g. It should not ring when in a meeting.
