Re: how can i control jini client to acccess entries in my javaspace?

hi,calum
   thank you for your kindness!
   I think my previous letter is not very precise, i want the control
action
take place in the server side(for example, blitz), not the client. in
another
word, i store some important message in my javaspace, i hope some specified
clients
can read these entries, others not.
   i think policy file which is used to control codes downloaded from remote
servers.
best regards
byron lee


BTW:
    can you tell me you blog url? i expect your next blog showing how to
 encrypt the entries.
