The Definitive Guide to Java RTS for Developers and Architects
Sun Microsystems’ Java Real-Time System (Java RTS) is proving itself in numerous, wide-ranging environments, including finance, control systems, manufacturing, and defense. Java RTS and the RTSJ standard (JSR-001) eliminate the need for complicated, specialized, real-time languages and operating environments, saving money by leveraging Java’s exceptional productivity and familiarity.
In Real-Time Java™ Programming, two of Sun’s top real-time programming experts present the deep knowledge and realistic code examples that developers need to succeed with Java RTS and its APIs. As they do so, the authors also illuminate the foundations of real-time programming in any RTSJ-compatible environment.
Key topics include
