A WebGroup/Virtual Host to handle / has not been defined

Hi,
I'm getting the following response code (error 404) when I try to connect to the RAM server via a Java httpclient.
What could be the problem?
Thanks for your help...

I am guessing you are not accessing the correct path to you RAM application. Check the extensions page for the correct URL. If you are sure the port is right it may be at http://localhost:13080/ram (Web app that uses FORM based authentication) or http://localhost:13080/ram.ws (web services WAR that uses BASIC auth).

It looks like you are trying to access the root of the web server http://localhost:13080 with no application context.

Thanks it works now - I needed to use BASIC auth
