Re: Class Server requests

Command line:

java -classpath .;..\lib\jini-core.jar;..\lib\jini-ext.jar -Djava.security.policy=..\policy.all com.mebigfatguy.jinitest.JiniTestService

Setting codebase

 public static void main(String[] args) {
  try {
   System.setSecurityManager (new RMISecurityManager ());
   
   int port = Integer.valueOf(args[0]).intValue();
   JiniClassServer cs = new JiniClassServer(port);
   cs.start();
   InetAddress.getLocalHost();
   System.setProperty("java.rmi.server.codebase", "http://" + InetAddress.getLocalHost().getHostAddress() + ":" + port);

   discovery = new LookupDiscovery(LookupDiscovery.ALL_GROUPS);
   leaseManager = new LeaseRenewalManager();
   
   discovery.addDiscoveryListener(new JiniTestDiscoveryListener(leaseManager));
   
   JOptionPane.showMessageDialog(null, "Shutdown service");
  } catch (Exception e) {
   e.printStackTrace();
  }
 }

Installing service

 public void discovered(DiscoveryEvent event) {
  try {
   ServiceRegistrar[] registrars = event.getRegistrars();
 
   Entry[] attr = new Entry[1];
         attr[0] = new Name("JiniTest");

   ServiceItem item = new ServiceItem(null, new JiniTestImpl(), attr);
   LeaseListener listener = new JiniTestLeaseListener();
 
   for (ServiceRegistrar registrar : registrars) {
     ServiceRegistration reg = registrar.register(item, Lease.FOREVER);
     leaseManager.renewUntil(reg.getLease(), Lease.FOREVER, listener); 
   }  
  } catch (RemoteException re) {
   re.printStackTrace();  
  }
 }
