Re: [Jgroup-users] Group discovery

[Hein M. <me...@ac...>]

Hi Brian,

Currently it is not supported.  That is you have to specify all server
hosts in the config file.  Clearly, clients need not be specified, but
clients typically need access to the config file to determine which
servers to probe.  The reason for this design is that Jgroup is designed
for use in WAN environments, in which group discovery without a config
file would be very difficult (if you know a solution, let me know). 
Furthermore, we have the ARM framework which is used to deploy replicas
seamlessly (following some rules) on the set of hosts specified in the
config file.

However, if your need is purely LAN and you decide to fix your replicas
on pre-selected server hosts we could perhaps solve this group discovery
issue without a config file.

It would be nice to know your particular need for such functionality.

Ciao,

  Hein
