Real-time Extensions for the Java^TM Platform

This is an informal collection of links that I maintain about real-time extensions to the Java^TM platform. The official web site for information on this topic is http://www.rtj.org/. Anyway, here's some information that I have collected:

• Sun is be working with members of the real-time community to define real-time extensions to the Java^TM platform. This is being done through the Java Community Process. A A Java Specification Request has been accepted. James Gosling is Sun's expert in this group. For more information about the real-time expert group's work, please see their web site, http://www.rtj.org/.

• I give presentations from time to time on Sun's view of real-time and the Java^TM platform, from the standpoint of the EmbeddedJava^TM and PersonalJava^TM group. For the slides, please remember that they're just slides! They don't stand by themselves, and removed from the context of the talk they might be misleading. If in doubt about any of the content, please ask me :-)
  • Slides from a presentation in May '99 given at AFNOR in Paris are avalable here, in PDF.
  • A postion paper for a panel at the ISORC '99 conference in St. Malo in May '99 is available here, in PostScript.
  • Slides and a position paper for the Santa Barbara WORDS '99 conference in January '99 are available. You can get the slides in PDF format, and the position paper in PostScript.
  • A position paper for a panel at the RTSS '98 conference in Madrid is available here, in PostScript.

• Sun participates in the NIST Requirements Working Group for Real-time Extensions for the Java^TM platform.

• To help advance debate in the requirements group, Sun produced a straw-man proposal. This shows the level of abstraction of what we'd like to produce, but it is not a polished proposal! Parts of it are almost certainly going to be removed. For example, the notion of pre-allocated object pools is most likely going to go. Per-threadgroup resource limits are also highly questionable.

  Internally, thinking has evolved considerably since this was written. If you'd like to see our updated ideas, or participate in the devlopment of the real spec, I strongly recommend that you sign a JSPA and join the community process.
