Sun Microsystems is gradually providing more details on how it plans to open source its core Java technology, delivering on a promise the company made to developers back in May at its JavaOne conference.The vendor intends to make both Java Platform Standard Edition (Java SE) and Java Platform Micro Edition (Java ME) freely available in "the November time frame," Peder Ulander, vice president of software marketing at Sun, said in an interview Tuesday.An open-source development initiative for building an application server based on the third member of the Java family, Java Platform Enterprise Edition (Java EE), has been under way since June 2005 under the name Project GlassFish.Sun intends to open source three main components of, respectively, Java SE and Java ME, Ulander said. For Java SE, the pieces are Java Compiler, JavaHelp and the Java HotSpot virtual machine. For Java ME, the components are the Connected Limited Device Configuration stack, the Connected Device Configuration and the Mobile Information Device Profile 2.1.Motorola Tuesday announced its plans to establish a Java ME open-source community for the mobile devices industry, voicing a hope to stem the fragmentation of the Java mobile platform.While Sun always intends to have technology branded Java, it\u2019s likely that work the open-source community does on the freely available versions of Java SE and Java ME will be known by project names, just like Java EE\u2019s Project GlassFish, Ulander said.Once Sun has open sourced Java, the company will have made 70 percent of its entire software portfolio freely available, Ulander said. Sun "is still on track" to open source all its software within 12 months, he added, with the remaining 30 percent consisting of the vendor\u2019s service-oriented architecture (SOA) suite and its identity management software. "We\u2019re already down that path," Ulander said\u00a0of open sourcing both the SOA and ID offerings, since Sun has previously made both its business process execution language engine and its single sign-on technology freely available.Open sourcing its software is Sun\u2019s "seeding model" to encourage more developers to experiment with its technologies, Ulander said. The hope is once enterprises decide to adopt Sun software, they\u2019ll want to pay for maintenance and support services and then also look at its hardware and storage offerings, driving up the company\u2019s revenue.Ulander cited Sun President and Chief Executive Officer Jonathan Schwartz\u2019s claim that the vendor\u2019s software drives 90 percent of the company\u2019s hardware sales. So far, Sun hasn\u2019t gone out of its way to illustrate that connection, but Ulander said the company is readying four case studies of Hewlett-Packard server customers who first tried out, then moved to Sun\u2019s OpenSolaris open-source operating system and over time also migrated to Sun\u2019s x86 servers.Sun plans to begin breaking out software sales when it reports its financial results, according to Ulander. That breakout will probably start appearing once the vendor closes its current fiscal year in June 2007, he said.-China Martens, IDG News Service (Boston Bureau)Related Links:\n\nMotorola to Build Open-Source Java ME Community\n\nSun Updates Java IDE With More Productivity Tools\n\nSun Inches Closer to Open-Source JavaCheck out our CIO News Alerts and Tech Informer pages for more updated news coverage.
