Weapon System Software Technology Support (WSSTS). Delivery Order 0008: Real-Time Java for Embedded Systems (RTJES)

Abstract : The Real-Time Java for Embedded Systems (RTJES) Program identified features of Real-Time (RT) Java suitable for meeting the challenges of future embedded information systems and defining the requirements of these features within the infosphere domain. After an initial survey of RT Java implementations, this program benchmarked the first commercially available RT Java implantation to provide an early assessment of the suitability of RT Java in the distributed real-time embedded system domain. Benchmarking efforts focused on assessing the performance and determinism of systems using RT Java. Two sets of tests were used. One examined characteristics of individual Real-Time Specification for Java (RTSJ) features. The other investigated performance within an environment representative of an avionics application. The RTJES program also performed a laboratory demonstration that showed the operational benefit of RT Java for network-centric applications. The demonstration highlighted RT Java code mobility, distribution, and portability.
