  • 1. The State of JavaArun GuptaJava Developer Advocate, Oracle
  • 2. The following is intended to outline our generalproduct direction. It is intended for informationpurposes only, and may not be incorporated intoany contract. It is not a commitment to deliver anymaterial, code, or functionality, and should not berelied upon in making purchasing decisions.The development, release, and timing of anyfeatures or functionality described for Oraclesproducts remains at the sole discretion of Oracle.
  • 3. Thank you Africa!
  • 4. Oracle Strategy • Deliver a complete, open, integrated stack of hardware, infrastructure, database, middleware, and business applications • Exploit processor, systems, storage, and networking trends to deliver breakthrough innovations by combining Oracle software with Sun hardware • Integrate components of Oracle’s software stack to provide unique value to customers
  • 5. Open Source Strategy ComparisonOracle doesn’t really have an open Whats the business model? Isource-specific strategy. What we dont know. But if you donthave is an overall company have adoption, it wont matterstrategy: to deliver complete, what business model youopen, integrated solutions to our use. Companies that sellcustomers. Stacks of software and open source are prioritizinghardware that are built together community and adoptionand tested together and serviced over instant monetization.together. And open source is partof that. - Edward Screven, Chief Corporate Architect - Jonathan Schwartz, CEO http://news.cnet.com/8301-13505_3-9757417-16.html http://www.oracle.com/technetwork/issue-archive/2010/o40interview-086226.html
