JavaSpaces
JavaSpaces, from the same people who brought you RMI,
is a distributed persistence and data exchange
mechanism for Java. You write data
in entries that are composed of a typed grouping of
fields. Clients operate on a
JavaSpace to write new entries, look up existing entries, and
remove entries from the space. This allows Java programs to store
their state.
In particular it allows applets to store state on servers when they
can't store it on the client because of security restrictions.
JavaSpaces has now been rolled into JINI for ubiquitous,
transient, networked computing.
