RMI problem with Localhost

[J You]

Hi,I am testing an RMI application with my home
computer.This application is the Calculator example
from tutorial at Sun Java site.In the server program,
the code is like following
Calculator c = new CalculatorImpl();
Naming.rebind("rmi://localhost:1099/CalculatorService", c);
But when I run the client program,it got the
ConnectException:
java.rmi.ConnectException: connect refused to host: 152.163.0.0;Nested Exception is
java.net.ConnectException: Operation Timed out : connection
I think the problem is the TCP/IP configuration of
my home computer.This is a brand new computer and
I use dial connection to access Internet.It seems
in the RMI,it resolves the localhost to "152.163.0.0"(the ISP ip address?),which then
refues the connection.
If I ping localhost,I can get 127.0.0.1
when I ping the computer name,I get the 152.163.0.0
I also installed the Tomcat in the computer,and I
can access http://localhost:8080 (but the shutdown.bat fails,and I guess the reason is also
the localhost stuff)
following is the output of "ipconfig -all" command:

Also,I checked the file /Windows/System32/etc/hosts and it does have
127.0.0.1 localhost

The easiest workaround is to substitute 'localhost' with '127.0.0.1' -- should work just fine then.
That is, by the way, an ugly IP address you're being given. It's a network number (i.e., the address that identifies the network itself, not any one station) but if it's working then your ISP may be doing some hinky routing thing.

You are using dialup connection to acceess to internet. That's why you PPP adapter in ipconfig.
You can assign ip address to your ethernet card starting with 10.10.10.x like 10.10.10.1 these are addresses assigned for intranet working and will not create clash outside world. Once you assign address then you can assign name in your host file like :
10.10.10.1 your_host_name
Then you can accesshttp://your_host_name ort# from your browser or any other protocol. Do not forget to change netmask to 255.255.255.0 otherwise you will not get host#.

Thanks,
After I assigned the 10.10.10.1 as the IP address
in the TCP/IP protocol property,all problems
disappeared.
I noticed the IP address was specified to
152.163.0.0.Still don't understand who originally set the static IP address,
the Computer manufactur,WinXP or the Dialup ISP?
Anyway,I am just very glad that the problems get
solved.

Hi I am also faced with the similar kind of problem.

Any solutions ??

I had the same problem, and after I assigned the IP address on my machine to 10.10.10.1 (just like J You above), it works fine for me too.
Thanks.
