The Jini™ technology provides an infrastructure for spontaneous networking of devices based on Java-classes and - interfaces. With the help of Jini, small devices with minimal resources should be able to join such infrastructures. Due to the fact that Jini is based upon RMI (Remote Method Invocation) and is therefore on top of RMI, it is impossible to Jini-enable these limited devices: the use of RMI by Jini wastes resources which are not available in the aforementioned limited devices. A potential approach to Jini-enable limited devices is to replace the RMI-technology with the RPC-technology (Remote Procedure Call). By means of this technology it is possible to provide an efficient mode of communication for Jini components, i.e. services and their proxies. However it is important to bear in mind, that this technology avoids the major part of resource waste. A revision of the implementation strategy for this reason and to adapt the Jini technology to the KVM/CLDC is necessary. In the following sections, the integration of an RPC-implementation into the Jini concept and some revised structures of the Jini-implementation strategy will be described.
