access to localhost:8080 fails
Hello,
I've a 6.0.26 (latest) Tomcat installed on my laptop (windows vista
ulltimate). When inside corporate network, it works. In home network, it
doesn't. Strange enough that it does not work even when the laptop stands
alone (not connected to any network). Accessing
http://localhost:8080results in: ERROR_INTERNET_CANNOT_CONNECT as seen
with HttpWatch. The
request does not reach the server (hence no log). server.xml has not been
changed.
netstat -ab shows the following processes:
TCP 0.0.0.0:8009 hostname:0 LISTENING
[java.exe]
TCP 0.0.0.0:8080 hostname:0 LISTENING
[java.exe]
: Windows Sockets initialization failed: 5
TCP [::]:8009 WDFN00224028A:0 LISTENING
[java.exe]
TCP [::]:8080 WDFN00224028A:0 LISTENING
[java.exe]
Windows host file has the following entries:
127.0.0.1 localhost
::1 localhost
Using java version "1.6.0_18"
The problem appears to be very strange to me. Did a lot of searching on the
web before this post. Nothing helped. I'm sure that this is not a new
problem and hoping that one of you have already solved such an issue.
Cheers,
Krish

I have seen similar issues on our corporate (XP and Vista) laptops, somebody
decided that the locally running firewall should also block access to
localhost. I think you should first verify if that's the case.
I'm not a Windows expert, so I don't know how to check if the above is the
case.
If you are allowed to give the netstat command, try the suggestion from
Charles (netstat -ano), if you see status SYN_SENT, it's for sure a firewall
issue.

Do you have localhost defined in that machine's hosts file?
Can you ping localhost from a command prompt?
What does netstat -ano show on the personal laptop?
You might be having IPv6/IPv4 problems. Try changing the hosts entry to just 127.0.0.1, leaving out the IPv6 setting.

I'm connected to a router via a wireless network which in turn connects me

I will now look into the problem from this direction as well. Thank you.

Sounds like whatever security agent you're using imposes different firewall rules depending on whether or not you're attached to the corporate network. (The one we use - SEP - certainly does.) You'll have to figure out how to change the firewall config - if you're allowed to.

http://localhost:8080 OR http://127.0.0.1:8080 works in one network
(corporate) and the same does not work in a different network (my home
network - wireless network for home from T-phone)

In my home network, I'm connected to via a router to the internet. The point
is that Tomcat is installed locally on my laptop and it should work without
any such connectivity. Unfortunately it doesn't.

That was a formatting mistake. I meant only http://localhost:8080
This request to the local server results in ERROR_INTERNET_CANNOT_CONNECT as
seen
with HttpWatch.

Thank you for helping me on this. The same setup on the same laptop will
start working tomorrow when I am connected to corporate network. This is a
corporate laptop and windows firewall is installed. But I am not sure where
should I look in to check if this firewall is the blocker. Moreover, I may
not be allowed to turn this firewall off even if it is required. By the way,
i turned it off temporariry (for 5 mins, hope nothing has happened in
between) but the situation did not change.

Can you explain how exactly "it works" ? what URL are you using then,
from where ? what are you seeing then ?

Same questions.

I presume this URL really is :
http://localhost:8080/results
, right ?

What does that mean ? What is is in the Tomcat logs, corresponding to
this error ?

Is the "Windows firewall" or anything similar enabled (AUP or whatever
it's called) ?
If you do NOT start the Tomcat Service, and do a "netstat -ab", what do
you see then ?

In what folder is this Tomcat instance installed?
With what user account it runs?
Do you run it as a service, or starting from a *.bat file, or from
inside an IDE?
There are two vista-related items on the FAQ page here:
