Initial Naming Context
The following example shows how to add names to the name space.
plans
Personal
calendar
schedule
import java.util.Properties;
In this example, plans is an object reference and Personal is a naming context that contains two object references: calendar and schedule.
import org.omg.CORBA.*;
import org.omg.CosNaming.*;
public class NameClient {
public static void main(String args[]) {
try {
Properties props = new Properties();
In Start the Naming Service, the nameserver was started on port 1050.
props.put("org.omg.CORBA.ORBInitialPort", "1050");
ORB orb = ORB.init(args, props);
NamingContext ctx =
This code obtains the initial naming context and assigns it to ctx.
NamingContextHelper.narrow(
orb.resolve_initial_references("NameService"));
NamingContext objref = ctx;
NameComponent nc1 = new NameComponent("plans", "text");
This code creates a name plans of type text and binds it to the dummy object reference.
NameComponent[] name1 = {nc1};
ctx.rebind(name1, objref);
System.out.println("plans rebind successful!");
NameComponent nc2 = new NameComponent("Personal", "directory");
This code creates a naming context called Personal of type directory.
NameComponent[] name2 = {nc2};
NamingContext ctx2 = ctx.bind_new_context(name2);
System.out.println("new naming context added..");
NameComponent nc3 = new NameComponent("schedule", "text");
The remainder of the code binds the dummy object reference using the names schedule and calendar under the Personal naming context (ctx2).
NameComponent[] name3 = {nc3};
ctx2.rebind(name3, objref);
System.out.println("schedule rebind successful!");
NameComponent nc4 = new NameComponent("calender", "text");
NameComponent[] name4 = {nc4};
ctx2.rebind(name4, objref);
System.out.println("calender rebind successful!");
} catch (Exception e) {
e.printStackTrace(System.err);
}
}
}
import java.util.Properties;
The following sample program shoes how to browse the name space.
