The goal of this paper is to assess the value of simplefeatures that are widely available in off-the-shelf CORBAand Java platforms for the implementation of fault-tolerancemechanisms in industry-grade systems. Thiswork builds on knowledge gained at LAAS from previouswork on the prototyping of reflective fault tolerantframeworks. We describe how we used the interceptionand state capture mechanisms that are available inCORBA and Java to implement a simple replicationstrategy on a small middleware-based system built uponGNU/Linux and JOrbacus. We discuss the benefits andthe limits of the resulting system from a practical point of view.
