Question

Im working now on simple gui appllication in Java/C++ and CORBA. I want my client on VirtualBox connect to server on localhost. When I have a simple app, like a calc I wrote about earlier its just fine. But when it comes to run client which needs some args witch javas -cp option, Im getting errors. (Theres no such problem when I have both client and server on localhost!) Im using Win XP on VirtualBox and Ubuntu on localhost.

My errors:

WARNING: "IOP00100007: (BAD_PARAM) string_to_object conversion failed due to bad

make[1]: *** [run] Error 1

ClientConnection.java:57 is a line objRef = clientORB.resolve_initial_references("NameService");
Client.java:295 is a line: ClientConnection.connect(args);

A connect method is just an ordinary client-connection corba code.

I ran my example:

1)
C:\Temp\Client>java -cp .:../Dir1:../Dir2 Client -ORBInitRef NameService
=corbaloc::192.168.56.1:2809/NameService
Error: Could not find or load main class Client so its even didnt run at all ..

2) with the help of a Makefile:

HOST = 192.168.56.1
PORT = 2809
NAMESERVICE = NameService

run:
    java -cp .:../Dir1:../Dir2 Client -ORBInitRef NameService=corbaloc::$(HOST):$(PORT)/$(NAMESERVICE) 

by typing make run and then I got those error I posted earlier. Whats wrong? I mean, a simple code works fine but gui version doesnt want to … is there a problem with -cp option? I cant change my apps’ dir tree.

Answer 1

I personally see two problems you have.

1. the classpath thing. Do you hava a file named Client.class in . or Dir1 or Dir2. If not, look for it and add it’s dir to the classpath. If it is in, please provide more information

2. The CORBA thing; I would like to see your Orb.init(); call. Everything else looks good.
