Editing JavaOS (section)

== History ==

The [[Java (programming language)|Java]] programming language was introduced by Sun in May 1995. Jim Mitchell and Peter Madany at JavaSoft designed a new operating system, [[codename]]d Kona, written completely in Java. In March 1996, Tom Saulpaugh joined the now seven-person Kona team to design an [[input/output]] (I/O) architecture, having come from Apple as Macintosh system software engineer since June 1985 and co-architect of [[Copland (operating system)|Copland]].<ref name="Inside the JavaOS">{{cite book |last1=Clements |first1=Tom |last2=Mirho |first2=Charles |date=January 1999 |title=Inside the JavaOS Operating System |series=Java series |publisher=Addison-Wesley |isbn=0-201-18393-5 |oclc=924842439 |others= |url-access=registration |url=https://archive.org/details/insidejavaosoper00saul}} [https://www.amazon.com/Inside-JavaOS-TM-Operating-System/dp/0201183935/ Preface text]</ref>{{rp|XI-XIII}}

JavaOS was first announced in a ''[[Byte (magazine)|Byte]]'' article.<ref name="Mirho:1997:JTC">{{cite journal |last1=Mirho |first1=Charles |last2=Clements |first2=Tom |title=JavaOS: Thin Client, Fat Service |quote=JavaOS uses a small memory footprint, yet its network-centric design lets it access large-scale services |journal=Byte |date=July 1997 |volume=22 |issue=7 |pages=53–54 |url=https://vintageapple.org/byte/pdf/199707_Byte_Magazine_Vol_22-07_User_Interface.pdf#page=57 |issn=0360-5280}}</ref> In 1996, JavaSoft's official product announcement described the compact OS designed to run "in anything from net computers to pagers".<ref name="announce"/> In early 1997, JavaSoft transferred JavaOS to SunSoft. In late 1997, Bob Rodriguez led the team to collaborate with [[IBM]] who then marketed the platform, accelerated development, and made significant key architectural contributions to the next release of JavaOS, eventually renamed JavaOS for Business.<ref name="Inside the JavaOS"/>{{rp|XI-XIII}}<ref>{{cite news |last=Hayes |first=Mary |title=Sun Enlists IBM For JavaOS Aid |url=http://www.informationweek.com/670/70iusun.htm |work=[[InformationWeek]] |date=February 23, 1998 |access-date=December 16, 2011 |url-status=dead |archive-url=https://web.archive.org/web/20001205014000/http://www.informationweek.com/670/70iusun.htm |archive-date=December 5, 2000 }}</ref> IBM indicated its focus was more on network computer [[thin client]]s, specifically to replace traditional [[IBM 3270]] "green screen" and Unix [[X terminal]]s, and to implement single application clients.<ref>{{cite web |url=http://www.itmweb.com/f031098.html |title=Inside the IBM JavaOS Project |access-date=December 16, 2011 |last=Finney |first=Russ |date=March 10, 1998 |work=itmWEB }}</ref>

[[ChorusOS|Chorus]], a distributed real-time operating system, was used for its microkernel technology.<ref name="Inside the JavaOS"/>{{rp|XIII}} This began with [[Chorus Systèmes SA]], a French company, licensing JavaOS from Sun and replacing the earlier JavaOS hardware abstraction layer with the Chorus microkernel,<ref name="ci-leaves">{{cite news |title=Chorus Leaves Unix Behind; Refocuses on Java and CORBA |work=[[Computergram International]] |issue=3112 |date=March 4, 1997<!--, CGN03040018.--> |via=Gale General OneFile |url=https://link.gale.com/apps/doc/A19171416/ITOF?u=wikipedia&sid=bookmark-ITOF&xid=c9b0d53b |access-date=June 1, 2021}}</ref> thereby creating the Chorus/Jazz product, which was intended to allow Java applications to run in a distributed, real-time embedded system environment.<ref>{{cite news |url=https://www.eetimes.com/chorus-systems-announces-chorus-jazz/# |title=Chorus Systems Announces CHORUS/JaZZ |magazine=EE Times |date= February 20, 1997}}</ref> Then in September 1997, it was announced that Sun Microsystems was acquiring Chorus Systèmes SA.<ref name="eetimes-1997">{{cite news |url=https://www.eetimes.com/sun-expands-network-software-business-into-embedded-systems-market/# |title=Sun Expands Network Software Business Into Embedded Systems Market |magazine=EE Times |date=September 11, 1997}}</ref>

In 1999, Sun and IBM announced the discontinuation of the JavaOS product.<ref name="CNet">{{cite news |last=Shankland |first=Stephen |title=Sun, IBM decaffeinate JavaOS |url=http://news.cnet.com/2100-1001-230175.html |work=[[CNet News]] |date=August 23, 1999 |access-date=December 16, 2011 }}</ref> As early as 2003, Sun materials referred to JavaOS as a "[[Legacy system|legacy technology]]", recommending migration to [[Java ME]], leaving the choice of specific OS and Java environment to the implementer.{{citation needed|date=March 2019}}
