The JXTA Shell is a sample application that demonstrates key concepts
of JXTA JXSE. The JXTA Shell enables users to interact with the JXTA
platform through a command-line interpreter. Much like the UNIX® shell,
the JXTA Shell is useful for accessing and managing core platform objects
(peers, groups, pipes), debugging communications problems, checking the
status of peers and/or peer groups, and communicating with other JXTA
services and applications. As in UNIX®, the JXTA shell allows users to
"pipe" shell commands together connecting commands "on-the-fly." Pipes
in Project JXTA are useful for collecting information at one peer and
perhaps processing the command at another.
