Hi:

People who are reading this forum might be interested to know that, today,
Sun released the General Availability (GA) version of Java Real-Time System
(Java RTS) 2.2, and that free evaluation versions are available for downloading:

# [http://java.sun.com/javase/technologies/realtime/index.jsp]
# [http://java.sun.com/javase/technologies/realtime/rts/]

When you select a Java RTS 2.2 eval through the latter link, the download link
will be sent to you by e-mail after you fill out and submit a quick survey. As part
of the download process, you'll also need to agree to the terms of a click-through
evaluation e-license -- an academic license for evaluators at any educational
institutions and a 90-day license for any other evaluators.

The supported platforms for Java RTS 2.2 are:

# Solaris10 (SPARC, x86), Update 6 and 7
# Linux (x86), SUSE Linux Enterprise Real Time and RedHat Enterprise MRG

For both OS categories, Java RTS 2.2 provides both 32-bit and a 64-bit support.
For more information on OS support and new features/functionality introduced in
Java RTS 2.2, please see the Release Notes for Java RTS 2.2:
