Such Distributed object technology as CORBA, DCOM, and Java RMI do not improve directly the reliability of distributed application. it require replication group management of object unit and fault detection and recovery mechanism that distributed object technology has fault tolerance. In this paper, we design group manager and remote interface, and define a fault-tolerant class to develop the fault-tolerant Java RMI object. In order that a fault-tolerant class participate transparantly in a group, we should expend the naming class and RMIRegistry. Because of inheritance from a fault-tolerant class, a application developer can make easily fault-tolerant application object without any other service assistance.
