Kurt i am not able to change DNS name of server to "sales"
i am doing by editing "juddiv3.properties" from cmd but it wont do

*i am not able to change DNS name of server to "sales"*
/OK, since you are trying hard, and it's a nice day out/, here is some
web basics:
Taken from: http://en.wikipedia.org/wiki/Uniform_resource_locator the
URL syntax is:
scheme://domain:port/path?query_string#fragment_id
So in this case 'sales' in the domain, and we know the web/appserver
runs on your own machine. So you do you get DNS to believe that the
domain 'sales' resolves to your machine? You can go a registrar (let's
say godaddy.com) and buy the 'sales' domain, and then have them resolve
'sales' to your IP address. Well 'sales' isn't even a valid domain. It
would have to be sales.com or something, and I'm sure that's taken. So
what to do?
It turns out you can override whatever DNS servers say by adding entries
in a hosts file. On linux you would find that file in /etc/hosts. On
windows it is a bit harder to find, Google tells me it lives in
C:\windows\system32\drivers\etc\ or %systemroot%\system32\drivers\etc\.
So now if we add
a line
sales 127.0.0.1
in that file. That machine will resolve sales to 127.0.0.1, which is the
loopback address, see
http://en.wikipedia.org/wiki/Localhost
which is your machine :).
Your next question will be, *but what about 'marketing'*?.
Marketing runs on your friend's computer, which let's pretent has IP
address 192.168.1.8. You can read about private networks here
http://en.wikipedia.org/wiki/Private_network (192.168.x.x is an example
of a private network address). So anyway, if he runs another juddi
server on his machine, you should be able to access it at :
http://192.168.1.8:8080/juddiv3, but you will say:"but that is not
'marketing'". For that you will need to add another line to *your* hosts
file:
marketing 192.168.1.8
Now on *your* machine, and on your machine only
http://marketing:8080/juddiv3 will resolve to your friend's machine.
Which is exactly what the subscription example is trying to do. To make
your friends machine resolve to your machine you will need to modify the
hosts file on your friends machine by adding a line
sales 192.168.1.7
where 192.168.1.7 is your IP address.
The only thing left for you to ask is: but how do I know what my IP
address is? For that you can use a command called 'ifconfig' on linux
and 'ipconfig' on windows.
You can tests that it works by using a command call 'ping'. So on the
marketing machine you can do
ping marketing
and it should say something like
ping marketing
PING marketing (127.0.0.1): 56 data bytes
64 bytes from 127.0.0.1: icmp_seq=0 ttl=64 time=0.046 ms
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.150 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.117 ms
Have fun learning about the wonderful world of networking. Not that any
of this has anything to do with UDDI.
