Dennis, can you add any additional information about how configurations of
multiple things are put together in either single files, or how multiple files
are integrated together? I do like the simplicity and the power of this.
It might also be interesting to see if a Scala version would be interesting or
have any different capabilities since there are additional language features
there too.

Someone on the Jini-Users (or similar, I can't quite remember) a while

unworkable for obvious reasons.
I brought up the Groovy config support. Rio has switched over from the
Jini configuration file approach to now use Groovy classes. No
compilation is required, the Groovy classes are parsed when loaded by
the GroovyConfiguration utility. A simple example of a Groovy
configuration for Reggie follows:
@Component('com.sun.jini.reggie')
class ReggieConfig {
String[] getInitialMemberGroups() {
def groups = [System.getProperty(Constants.GROUPS_PROPERTY_NAME,
'rio')]
return (String[])groups
}
String getUnicastDiscoveryHost() {
return java.net.InetAddress.getLocalHost().getHostAddress()
}
}
