create several JavaSpaces

Hello.

I am using JINI as a techlology for simmulating whiteboard.

Right now I am using JINI 1.2 (because documents are on JINI 1.2, though
JINI 2.1 is better for security issue,
and I shall upgrade JINI version to the newer one).

I want to create several groups of users.

Should I create for that several Javaspaces (or there is always one) ?

How can I create several groups of users ?
Need sample codes, please.

Thanks :)

Please do not hijack the OP's thread. Eitan M was asking about Javaspaces.

JINI is one of Java's technology (used for mobile phones, communication
between remote computers,
and simmulates plug-and-play drivers for none-windows' platforms).
, and is not Chinese.

I think the answer related to ServiceItem class, and attitudes used by the
servers & clients.
There are not many samples arround the internet, so it is very difficult
issue to learn,
and I need some good examples, please (for Jini 1.2).

Thanks :)

Check out http://www.jini.org and Jan Newmarch's website for Jini
2.1 documentation. There shouldn't be any reason to use 1.2 on new
development.

If the volume of information can be held in one JavaSpace,
there's no need to create multiple instances. You'll want to
associate a blackboard ID with each JavaSpace Entry and have users
specify the ID in the template used to read or be notified of new
entries.

Do I have to write any changes in my code, in order to run on JINI 2.1 (from
1.2),
or it is old-compatible version, and I need change nothing about it ?

Thanks :)
