Error trying to connect to Jacorb naming service

I hope to get some help on this strange problem. We are launching the Jacorb name server, and I have a simple client that I use to try to connect and make awesome CORBA voodoo. The name server is running, but when I try to start the java application, I get "Connection failure" error (org.omg.CORBA.COMM_FAILURE, minor code 201, "caused by java.net.ConnectionException: Connection refused: connect").

Here's the weird part. The error reports that it is trying to connect using the default port of 900, but I am passing an argument to try to redefine the name service port number according to the one used by the name server. My java command looks like this:

java -classpath . HelloClient -Djava.endorsed.dirs="bla bla bla" <br>
-Dorg.omg.CORBA.ORBClass=org.jacorb.orb.ORB 
-Dorg.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton
-DORBInitRef.NameService=corbaloc::localhost:2809/StandardNS/NameServer-POA/_root

I also tried the parameters without the first capital D (I saw this in both directions, and I do not know the difference).

Now, if I put in -ORBInitialPort 2809, then the client is really trying to connect, but then I get an error corba.OBJECT_NOT_EXIST.

I could use any help or advice anyone has.

Disconnected. This sounds like a problem with the firewall / program. try it telnet <machine> 2809. You should get a "Connected to" link, and not a failure if everything works correctly.

I work on a UNIX client, so the paths use the UNIX style.

  • jacORB ? orb.properties( ${JAVA_HOME}/jre/lib/ "ORBInitRef.NameService=corbaloc::localhost:2809/NameServer" "NameServer" , "...."

    UNIX (.. e:\NS_Ref → /tmp/NS_Ref) jacorb.naming.ior_filename=/tmp/NS_Ref
