Jini Technology Core Platform (JCP), the Jini Technology Extended Platform
(JXP) and the Jini Software Kit (JSK).
Jini[tm] network technology provides a simple infrastructure for delivering
services in a network and for creating spontaneous interaction between
programs that use these services regardless of their hardware/software
implementation.

Sidenote: the package depends on revision 1.39 of
sys/compat/linux/common/linux_socket.c to work properly on NetBSD - for
the time being, it therefore contains
ONLY_FOR_PLATFORM= NetBSD-1.5Z[C-Z]-* NetBSD-1.[6-9]-* Linux-*-*
which can be commented out iff you use a kernel built using said file.
