Question: Do you know any P2P (peer to peer) projects like Napster, Morpheus based on Java?

Answer: Interest in peer-to-peer (P2P) technology is growing rapidly, as evidenced by the popularity of services like Napster, Gnutella, and SETI@home. Seeing the potential of P2P computing to enable access to a broader, deeper Web, Sun started a small research effort called Project JXTA.

Until recently, however, P2P technologies have been used primarily in singlefunction applications, such as instant messaging. Taking the concept of P2P much farther, Sun Microsystems founder and chief scientist Dr. Bill Joy conceived the idea of Project JXTA as a means of integrating P2P into the very core of the network architecture.

Project JXTA is a set of simple, open peer-to-peer protocols that enable any device on the network to communicate, collaborate, and share resources. JXTA peers create a virtual, ad hoc network on top of existing networks, hiding their underlying complexity [see Figure 1]. In the JXTA virtual network, any peer can interact with other peers, regardless of location, type of device, or operating environment - even when some peers and resources are located behind firewalls or are on different network transports. Thus, access to the resources of the network is not limited by platform incompatibilities or the constraints of a hierarchical client-server architecture.

Project JXTA technology espouses the core technology objectives of ubiquity,
platform independence, interoperability, and security. JXTA technology runs on any device, including cell phones, PDAs, two-way pagers, electronic sensors, desktop computers, and servers. Based on proven technologies and standards such as HTTP, TCP/IP and XML, Project JXTA is not dependent on any particular programming language, networking platform, or system platform and can work with any combination of these.

Question: Are classes implementing Externalizable considered Serializable classes?

Answer: Yes, since public interface Externalizable extends Serializable (according to API)
