P2P Sockets makes it easy to write peer-to-peer
applications based on JXTA. P2P Sockets allows
programmers to gain much of the power of JXTA, such
as NAT and firewall traversal, without being exposed
to its complexity. It does this through ports of
popular software projects, such as a web server and
web services stack, to work on the JXTA peer-to-peer
network. This includes a web server (Jetty) that can
receive requests and serve content over the peer-to-peer
network; a servlet and JSP engine (Jetty and Jasper) that
allows existing servlets and JSPs to serve P2P clients;
an XML-RPC client and server (Apache XML-RPC) for
accessing and exposing P2P XML-RPC endpoints; an HTTP/1.1
client (Apache Commons HTTP-Client) that can access P2P
web servers; a gateway (Smart Cache) to make it possible
for existing browsers to access P2P web sites; and a
WikiWiki (JSPWiki) that can be used to host WikiWikis on
your local machine that other peers can access and edit
through the P2P network. P2P Sockets also introduces
implementations of java.net.Socket and
java.net.ServerSocket that can work on the JXTA network
as well as a simple, light-weight, distributed,
human-friendly, and non-secure DNS system.
