Service-oriented development has gained much attention in recent years with the advent of technologies such as Web Services, .NET, and Jini. Standards for specifying, publishing, and delivering services has enabled approaches for specifying applications that can integrate and bind at run-time with services that meet application requirements. Jini is a service-based framework that was originally developed to support integration of devices as services. Web services are services that are delivered over the World Wide Web using WSDL as a descriptor and SOAP as the delivery mechanism. In this paper, we describe a wrapping technique that facilitates the integration of web services into Jini service applications on-the-fly. As a result, an application can take advantage of run-time service lookup facilities provided by Jini without needing ? priori knowledge of the web services it eventually uses.
