OPERATING SYSTEM(S):
Red Hat Enterprise Linux AS release 3 (Taroon Update 1) and Windows XP.

JAVA VERSION:
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b37)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b37, mixed mode)


When trying to use IPv6 loopback address (::1) in java.naming.provider.url

eg) -Djava.naming.provider.url=iiop://[::1]:2809

The following exception is thrown:
Trouble: javax.naming.ConfigurationException: Nonnumeric port number: [::1]:2809
javax.naming.ConfigurationException: Nonnumeric port number: [::1]:2809
        at com.sun.jndi.cosnaming.CNCtx.initUsingIiopUrl(CNCtx.java:302)

        at HelloServer.main(HelloServer.java:12)

Result:
Unable to run ORB tests with IPv6 address in numeric format.

Expected Result:
Should be able to process the IPv6 address in numeric format without any error/exception.

Steps to Recreate:
1) On a Windows XP Service pack 1, do the followign to enable IPv6.
Open a command prompt
Type ipv6 install
You should see the following
D:\svt\ipv6\test>ipv6 install
Installing...
Succeeded.
Type ping ::1 .You should see

D:\svt\ipv6\test>ping ::1

Pinging ::1 with 32 bytes of data:

Reply from ::1: time<1ms
Reply from ::1: time<1ms
Reply from ::1: time<1ms
Reply from ::1: time<1ms

Ping statistics for ::1:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 0ms, Maximum = 0ms, Average = 0ms

This is to confirm IPv6 loopback is responding.

2) Download and unjar test.jar
3) set CLASSPATH=.
4) javac *.java
5) rmic -iiop HelloImpl
6) start tnameserv -J-Djava.net.preferIPv4Stack=false -ORBInitialPort 2809
7) Start the server:
java -Djava.net.preferIPv4Stack=false -Djava.naming.factory.initial=com.sun.jndi.cosnaming.CNCtxFactory
-Djava.naming.provider.url=iiop://[::1]:2809 -Dcom.ibm.CORBA.Debug=true -Dcom.ibm.CORBA.CommTrace=true HelloServer

To recreate the problem on Linux follow steps from 2 to 7 on a machine which has IPv6 enabled.

                System.out.println(hello.sayHello());
        } catch (Throwable t) {
                t.printStackTrace();
        }
