Binding to the sessionScheduler (CORBA) Vs (RMI)

• CORBA Binding Process. private void getSessionSchedulerHandle() {

try {

// Initialize the ORB.

org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(this, null);

// Calculate Start time

long startTime = System.currentTimeMillis();

// Bind to the Scheduler Object

/* Get a reference to the Naming Service */

org.omg.CORBA.Object nameServiceObj =

orb.resolve_initial_references("NameService");

if (nameServiceObj == null) {

System.out.println("Name Service Object = null");

return; }

org.omg.CosNaming.NamingContext nameService =

org.omg.CosNaming.NamingContextHelper.narrow (nameServiceObj);

if (nameService == null) {

System.out.println("nameService = null");

return; }

NameComponent[] collabName =

{ new NameComponent("Collaboration", "Scheduler")};

_chatSession=

jdce.scheduler.sessionSchedulerHelper.narrow (nameService.resolve(collabName));

} catch(Exception e) {

System.out.println("Exception: " + e); } }

• RMI Binding Process

private void getSessionSchedulerHandle() {

try {

remoteObject =

Naming.lookup(

"rmi://jojo.npac.syr.edu:7000/Scheduler");

} catch (java.lang.Exception exec) {

System.out.println("Unable to lookup created Scheduler");

}

_chatSession = (jdce.scheduler.RMISessionScheduler) remoteObject;

}
