Recently, there has been increasingly demand for connecting a embedded device to the Internet. Jini technology is interested in automatically composing a distributed network with devices But, there are some problems that the device needs high hardware requirements to adopt Jini technology for supporting Jini-enabled services. In this paper, we focused on design and implementation of surrogate system that supports non-Java devices in Jini networks. This system and protocol are implemented in Java language. The surrogate system delegates Discovery and Join processing to support a Jini service in connected networks. A Jini client can use service of the device through the surrogate system. We tested a Jini sample program to verify the implemented surrogate system. In the test result, we showed that the Jini client can use functionalities and operations of the non-Java device through the surrogate system.
