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

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. customer .CORBA.Debug=true -Dcom. customer .CORBA.CommTrace=true HelloServer

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

            e.printStackTrace();

N/A

The current URL format that the cosnaming service provider uses conforms to the URL syntax defined in Interoperable Naming Server (INS) specification, OMG TC Document orbos/98-10-11. 
The cosnaming service provider must be enhanced to handle the IPv6 literal addresses in the IIOP URL.
