This paper addresses the need to reduce the difficulties in
developing time-constrained Java applications. We present a
design pattern for a class of time-constrained real-time
applications that allows developers to use (and re-use) Java code
libraries and non-developmental items (NDI). The proposed
design pattern simplifies the implementation of the timeconstrained
tasks substantially by not requiring the use of no-heap
real-time threads. We tested the design pattern with the Java Real-
Time System (RTS) 2.0 from the Sun Microsystems. This paper
also presents a simple methodology for determining the
appropriate values for the RTS run-time parameters (thread
priorities, memory usage, process load, and task deadlines) in
order to ensure the deterministic execution of the time-constrained
tasks.
