Question

Java/CORBA: ORB problems with simple Hello World application

Asked by: jchristn123

Hello,

I am testing a simple Hello World application using Java and CORBA (the source can be found at http://java.sun.com/j2se/1.4.2/docs/guide/idl/jidlExample.html

I've gone through all of the steps successfully (IDL to Java compiler, compiling the Java files) and so on, but when I try to run I get a series of errors.  On the surface it appears ORB is trying to use my fw0 interface (firewire interface, I'm using a Mac w/ OSX 10.5).  

Can you please help me with this?

Here's the output when I run the ORB:
$ orbd -ORBInitialPort 1050 -ORBInitialHost localhost
< no output >

Here's the output when I run the HelloServer application:
n$ java HelloServer -ORBInitialPort 1050 -ORBInitialHost 127.0.0.1

If you are not in one of these cases (and considering your comment about the networking interface), I would start looking at the orbd setup (adding -ORBServerHost for example). Two threads that might help (and have a few more ideas that might help):

Thanks Venabili: I tried the same on Windows with JDK 6u7 and it worked fine.  Must be an issue on my Mac.
