Problem in executing remote Java Swing client of an EJB application

[Sudhesh Rajan]

I am getting the following exception when i am trying to run my client code.

client code is running perfectly, when i tried it on the same system on which server is running. I am using WSAD 5.0.
is there any further settings required for running clients from a remote machine. Please, somebody help me out.

javax.naming.ServiceUnavailableException: A communication failure occurred while attempting to obtain an initial context using the provider url: "iiop://<mc-name>:2809". Make sure that the host and port information is correct and that the server identified by the provider url is a running name server. If no port number is specified, the default port number 2809 is used. Other possible causes include the network environment or workstation network configuration. Root exception is org.omg.CORBA.TRANSIENT: Connection refused: connect:host=<mc-name>.<my - company>.com,port=2809 minor code: 4942F301 completed: No


the code for looking up is:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL,"iiop://<mc-name>:2809");
Context ctx = new InitialContext(env);



Thanks & Regards

Because you are running your client on a remote host , please set the Server information in your InitialContext properties as
properties.put( javax.naming.Context.PROVIDER_URL,
"IIOP://remote_host_ip_address:2809/" );

hi all,
Thanks for your kind reply.
I tried it with the InitialContext properties as
properties.put( javax.naming.Context.PROVIDER_URL,
"IIOP://remote_host_ip_address:2809/" );


but again the same exception came. On adding namingserver.jar file the
previous exception has gone.
Now it is giving

javax.naming.CommunicationException: A communication failure occurred while attempting to obtain an initial context using the provider url: "corbaloc:iiop:remote_host_ip_address:2809". Make sure that the host and port information is correct and that the server identified by the provider url is a running name server. If no port number is specified, the default port number 2809 is used. Other possible causes include the network environment or workstation network configuration. Root exception is org.omg.CORBA.COMM_FAILURE: WRITE_ERROR_SEND_1 minor code: 49421050 completed: No

I think you did not use your real remote host name or ip address of the server which hosts your naming service to replace remote_host_ip_address string .

Hi Lin,

Once again Thanks for your kind reply.

I got the solution, actually i didn't set the BootstrapHostAddress from localhost to machine address that's why the problem was coming during execution.

If any one have the same type of problem with the deployment of client code then just go to the Adminconsole the to the server
in processdefinition change the value of BootStrapHostAddress from localhost to mc name then restart your server.


or you can change this value in serverindex.xml file also.

Thanks & Regards
