A follow-on overview paper was published in the ''[[Communications of the ACM]]''.<ref>{{cite journal | url=https://dl.acm.org/doi/abs/10.1145/276609.276619 | doi=10.1145/276609.276619 | title=Adding real-time capabilities to Java | date=1998 | last1=Nilsen | first1=Kelvin | journal=Communications of the ACM | volume=41 | issue=6 | pages=49–56 }}</ref> The overwhelmingly positive response to these early proposals resulted in a series of meetings hosted by the National Institute of Standards and Technology in an effort to establish an open standard for real-time Java. NIST was ultimately told that they were not the appropriate body to establish standards related to the Java language, as Java was trademarked, and the technologies were owned by Sun Microsystems. Therefore, NIST ended their efforts with publication of consensus requirements.<ref>{{cite journal | url=https://www.itl.nist.gov/div897/ctg/real-time/rtj-final-draft.pdf | title=Information Technology Laboratory | journal=NIST | date=28 April 2015 }}</ref> that could be considered by future standardization efforts to be hosted by Sun Microsystems.

When the [[Java Community Process|Java Community]] was formed, the very first effort was the specification for real-time Java, JSR001. A number of implementations of the resulting ''Real-time specification for Java'' (''RTSJ'') have emerged, including a [[reference implementation (computing)|reference implementation]] from [[TimeSys|Timesys]], [[IBM]]'s WebSphere Real Time, [[Sun Microsystems]]'s Java SE Real-Time Systems,<ref>[http://java.sun.com/javase/technologies/realtime/index.jsp Java SE Real-Time Systems]</ref> PTC Perc from [[PTC, Inc.]],<ref>[http://www.ptc.com/developer-tools/perc PTC Perc]</ref> or [[JamaicaVM]] from aicas.

==Real-Time Specification for Java==

The ''Real-Time Specification for Java'' (RTSJ) is a set of [[Interface (computer science)|interface]]s and behavioral refinements that enable real-time [[computer programming]] in the [[Java (programming language)|Java programming language]]. RTSJ 1.0 was developed as JSR 1 under the [[Java Community Process]], which approved the new standard in November, 2001. RTSJ 2.0 is being developed under JSR 282. A draft version is available at a JCP page.<ref>https://www.jcp.org/en/jsr/detail?id=282 JSR 282</ref> More information can be found from Aicas.<ref>{{Cite web | title=Real-Time Specification for Java {{!}} aicas.com | url=https://www.aicas.com/cms/rtsj {{Bare| URLarchive-url=https://web.archive.org/web/20150526085240/https://www.aicas.com/cms/rtsj inline| access-date=August2025-02-17 2024| archive-date=2015-05-26}}</ref>
