There are details on how to configure it at the end of this page:
http://docs.oracle.com/javase/7/docs/technotes/guides/net/ipv6_guide/index.html
Speaking of this guide, there are two problems with this as well:
First of all the Title is Java 5, but it is published in JDK 7
Documentation set as well. For the Java 8 I would recommend to overhaul at
least the title.
When touching that document anyway, there is one thing I find very
disturbing, the comparision between a Java Program and a "corresponding"
C-Program is not fair, as the new/old version of the C-Program both loop
over all possible addresses and the Java program does not. So in fact the
Java program does not work very well in Dual-Stack environements whereas
the C-program follow best practice.
Eighter add the Loop for the Java program as well (but then the notion
"sample from tutorial works" is a bit wrong) or maybe add something like
"however you might want to add additional support for trying different
potential addresses like...")
For the ServerSocket C-Code I would add ioctl(V6ONLY,0) to make that
obvious that Java is doing that always.
In the guide the is some mentioning of a V6ONLY option. Is there a plan to
offer it, or should maybe the guide be reworked a bit?
I also think we could remove the part about compatibility addresses, they
have been deprecated in RFC 5156 (unfortunately :)
What is the original source format of that document, is it somewhere
available I would take a shot on changing it.
Greetings
Bernd
PS: the lack of Happy Eyeballs support in Java will be a seperate Thread.
