Workshop for Real-time Java ™ Implementation Issues

Workshop for Real-time Java^(TM) Implementation Issues

Hosted by the

National Institute of Standards and Technology

Gaithersburg, Md.

Lecture Room D

June 25 - 26, 1998

Java^(TM) is being deployed in many information technology (IT) areas; far beyond the jazzy webpage applets. There are not many IT industries where Java is not being mentioned. Real-time applications and embedded systems are two areas that are more recently being addressed in the Java development arena. How do users with real-time requirements in both the embedded and client/server application environments use Java to meet their requirements? How can these users ensure that their requirements are being met correctly? The Workshop for Real-time Java Implementation Issues seeks to provide an open forum where both users and developers of real-time Java implementations can explore requirements, functionality, solutions and current offerings.

The National Institute of Standards and Technology (NIST) is hosting this workshop to discuss real-time requirements and solutions in Java environments. The purpose of the workshop is to bring together those interested in using Java technologies in their real-time applications and systems with those who offer solutions in utilizing Java in these environments.

Discussion topics that will be explored include:

What are the real-time requirements that can be addressed by integration of Java and real-time techniques?
What real-time applications and real-time environments can make use of the Java technologies?
What solutions exist, in terms of specifications, practices and testing to meet real-time implementation requirements?

Program managers responsible for meeting real-time requirements in applications and systems development and vendors utilizing Java in their real-time solutions are encouraged to attend this open workshop. Participants are expected to actively participate. Contact Lisa Carnahan, NIST, at (301) 975-3362 or lisa.carnahan@nist.gov for more information.

Workshop for Real-time Java^(tm) Implementation Issues

The Workshop for Real-time Java Implementation Issues was held on June 25-26 at NIST. Real-time applications and embedded systems are two areas that are more recently being
addressed in the Java development arena. The Information Technology Laboratory (ITL) at NIST hosted the workshop to discuss real-time requirements and solutions in Java environments. The workshop brought together those interested in using Java technologies in their real-time applications and systems with those who offer solutions in utilizing Java in these environments. An open forum was provided where both users and developers of real-time Java implementations explored requirements, functionality, solutions and current offerings. The presentations made by the speakers stimulated lively and productive discussion.

Vocabulary: The workshop participants reached consensus on the need for a common vocabulary. The workshop is using the vocabulary presented by Doug Jensen as a starting point. Discussions regarding the vocabulary are directed to rt-j@nist.gov.

Requirements: A set of Requirements for Real-time Java was developed by members of a panel organized the by the Rockwell Science Center. This set of requirements serves as the starting point for discussion regarding real-time requirements for Java. Additionally, Real-time Java Requirements, a paper written by Serdar Uckun of the Rockwell Science Center and Franco Gasperoni of Ada Core Technologies/ACT, raises core issues that need to be addressed in developing a set of real-time requirements for Java.

Specification: The workshop participants agreed to use, as a starting point, the specification proposed by Kelvin Nilsen of NewMonics. Discussions regarding the specification are directed to rt-j@nist.gov. For those of you familiar with the previous version of this specification, a redline comparison version is available.

Archive: The archive of the discussions related to real-time Java topics captures the ideas, comments and rationale that serve to move the industry forward. If you would like to join the rt-j@nist.gov discussion list please contact lisa.carnahan@nist.gov.
