assigning CORBA port to listen

[Robert Dodier]

Hello,

I am working with a program (namely the JADE agent platform
plus a plug-in; I didn't write any of it) which uses org.omg.CORBA
classes in a message transport scheme.
I notice via netstat that the port which is opened for listening
for CORBA requests appears to be allocated at random
(anything above 32768 apparently).
I would like to make the port fixed. Is there a method call in
some CORBA class or a system property or something I can
assign in order to specify the listening port?
I've looked at various documents and searched the web but
came up empty handed. Thanks for any information.

best

I suspect it's specific to the ORB you're using. Which ORB are you using?

There is a standard property called org.omg.CORBA.ORBInitialPort, which
you can set on your ORB in a number of standard ways - see:

http://java.sun.com/javase/6/docs/api/org/omg/CORBA/ORB.html

But i think that's the port the ORB uses to look for a naming service,
rather than the one it listens for IIOP on.

Hi,

for the record, it appears that the property
com.sun.CORBA.ORBServerPort specifies the port
on which the ORB listens. It can be specified on the
command line, e.g. java -Dcom.sun.CORBA.ORBServerPort=1234

By the way I am using the Sun ORB (bundled in the JDK).

Thanks for letting us know! Shame this isn't standardised across ORBs, or
document anywhere obvious.
