WEB SERVICES DEPLOYMENT ON P2P NETWORKS, BASED ON JXTA

Digital libraries require several different services. A common way to provide services to Digital Libraries is with the use of Web Services but Web Services are usually based on centralized architectures. In our work we propose that Peer-to-peer networks can be used to relieve the weight of centralized components on the Digital Library infrastructure. One of the challenges of this approach is to develop a method that allows the integration of existing web services into this new reality. In this paper we propose the use of a proxy that allows exposing Web Services that are only accessible trough the peer-to-peer network to the outside world. This proxy also manages interactions with existing external Web Services making them appear as part of the network itself, thus enabling us to reap the benefits of both architectures.
