Apache - Unable to load the application url

[Clekha]

Hello All.
Currently we upgraded our Jboss server from AS to EAP version with Apache as web servers,
Right now we are facing issue on browsing the URL ,

http://example.example.com/repgen/test/ Not working(Neither from server locally nor remotely)
But when we try to access [example...] or http://localhost/repgen/test/ its workig fine locally on the server,

Above URLs is intended to connect to WAR which deployed on different server.

We thought it could be DNS issue , but its doesn't seems like because we are able to browse Login page
http://example.example.com/login

Any help regarding this is highly appreciated.

we have modjk installed on apache server (servername - host) to loadbalance and connect to jboss server
Thanks!

What, exactly, does "not working" mean? Blank screen, error message, browser timeout? If it's an error message, where does it come from?

[Clekha]

Its error saying file not found.
Pls note, while loading the url [example...] from local server it works. we get the expected output.

OK, sit tight. We need someone who speaks Apache, and if they're all American you're out of luck for the next few days ;)

Is "Unable to load the application url" the actual text of your error message, or your own analysis? Is there an application involved? (Other than Apache itself-- plus any built-ins-- that is.)

Incidentally this question probably belongs in the Apache subforum-- didn't notice we aren't there already-- but don't repost. It's the same moderator either way.
