This is done in exactly the same way as in the first example of this chapter. In addition, it will need to 1. Register the lease listener (such as the previous RenewLease) with the activation system as an activatable object. 2. Find a LeaseRenewalService from a lookup service. 3. Register all leases from lookup services with the LeaseRenewalService. Since it may find lookup services before it finds the renewal service, it will need to keep a list of lookup services found before finding the service, in order to register them with it. package activation; import rmi.RemoteFileClassifier; import net.jini.discovery.LookupDiscovery; import net.jini.discovery.DiscoveryListener; import net.jini.discovery.DiscoveryEvent; import net.jini.core.lookup.ServiceRegistrar; import net.jini.core.lookup.ServiceItem; import net.jini.core.lookup.ServiceRegistration; import net.jini.core.lookup.ServiceTemplate; import net.jini.core.event.RemoteEvent; import net.jini.core.event.RemoteEventListener; import net.jini.core.lease.Lease; import net.jini.lease.LeaseRenewalService; import net.jini.lease.LeaseRenewalSet; Barcode Creator In None Using Barcode drawer for Font Control to generate, create Barcode image in Font applications. www.OnBarcode.comCode 3 Of 9 Creator In None Using Barcode maker for Font Control to generate, create Code 39 image in Font applications. www.OnBarcode.comCHAPTER 25 ACTIVATION
