public class ReggieLookup

extends SupportObject

This singleton will locate all reachable Jini Reggie Servers and store them for use by any requesting Client.

For environments that do not have multicast enabled (which Jini uses for discovery), or for enabling Unicast Discovery, create properties using the properties framework in the form of . . .

 
    hostNameOfAReggieService 
    hostNameOfAReggieService 
    hostNameOfAReggieService 
   . . .
 
 

. . . for as many Unicast Discovered Reggie services you wish to Discover. Multicast will still be used as well as Unicast.

This object utilizes the Singleton Design Pattern.
