The any value in the address attribute of the iiop-listener element in the server.xml file allows for listening on all interfaces that are available on a system. This support includes both IPv4 and IPv6 interfaces. However, the Sun ONE Application Server default configuration uses an address value of 0.0.0.0 in the iiop-listener element. This default configuration does not listen on IPv6 interfaces. The configuration only listens on all IPv4 interfaces on a system.
Workaround: Use the :: value in the address attribute of the iiop-listener element in the server.xml file to listen on all IPv4 and IPv6 interfaces on a system.
