Rmi iiop exception (orb)

Question

Hi,
When i run my program i receive an exception. The orbd tool is running on port 900. Stubs are created for iiop. The class extends the PortableRemoteObject. This exception arises when creating the initialContext with:
Properties p = new Properties ();
p.put (Context.INITIAL_CONTEXT_FACTORY,
   "com.sun.jndi.cosnaming.CNCtxFactory");
p.put (Context.PROVIDER_URL,"iiop://localhost:900");
InitialContext ctx = new InitialContext (p);The exception is:
javax.naming.CommunicationException: Cannot connect to ORB.  Root exception is org.omg.CORBA.COMM_FAILURE:   vmcid: SUN  minor code: 201  completed: No

Answer 1

I am trying to run a simple rmi over iiop server.
I started the tnameserv with
tnameserv -ORBInitialPort 2222
I am trying to run the server
static final String CONTEXT_NAME = "java.naming.factory.initial";
static final String IIOP_STRING = "com.sun.jndi.cosnaming.CNCtxFactory";
static final String URL_NAME = "java.naming.provider.url";
static final String IIOP_URL_STRING = "iiop://localhost:2222";
And in the main method
// Create and install a security manager
if (System.getSecurityManager() == null) {
System.setSecurityManager(new RMISecurityManager());
try {
// Create the IIOP Initial Context
Properties iiopProperties = new Properties();
iiopProperties.put( LFChallenger_SimImpl.CONTEXT_NAME,
LFChallenger_SimImpl.IIOP_STRING );
iiopProperties.put( LFChallenger_SimImpl.URL_NAME,
LFChallenger_SimImpl.IIOP_URL_STRING );
// create and initialize the ORB
ORB orb = ORB.init(args, null);
// initialize naming context
iiopProperties.put("java.naming.corba.orb", orb);
Context initialNamingContext = new InitialContext( iiopProperties );
LFChallenger_SimImpl obj = LFChallenger_SimImpl.getInstance();
// Bind the object to the IIOP registry
initialNamingContext.rebind("LFChallengerServer",obj);
System.out.println("LFChallengerServer bound in registry");
} catch (Exception e) {
System.out.println("LFChallenger_SimImpl err: " + getMessage ());
e.printStackTrace();
Running the server using
java -Djava.rmi.server.codebase=C:/CEMS/Corvis/home/TMF/cems_sim/src/java/classes/ -Djava.security.policy=policy -Djava.naming.provider.url=iiop://localhost:2222 -Djava.naming.factory.initial=com.sun.jndi.cosnaming.CNCtxFactory -classpath c:\Borland\AppServer\lib\vbjorb.jar; com.corvis.cems_sim.LFChallenger_SimImpl
And I am getting these annoying exceptions when I run the above command
LFChallenger_SimImpl err: COS Name Service not registered with ORB under the name 'NameService'
javax.naming.ConfigurationException: COS Name Service not registered with ORB under the name 'NameService'. Root exception is org.omg.CORBA.ORBPackage.InvalidName

Please help me with this problem
thanks
