Tomcat website deployment error

I have a tomcat website (octane generated) which I am trying to deploy on a devo box. The website loads up fine on my desktop. But when deploying on devo, it gives the following error in catalina.out log file :

It looks similar to this error http://www.coderanch.com/t/86776/Tomcat/tomcat, but I could not find a resolution after some digging around.

It would be great if you can throw some light on this, if it is a known issue. FYI, I have not made any changes to the server.xml, context.xml files and web.xml.

I'm just taking a wild stab in the dark here, but do you think this could have something to do with it:

java.io.FileNotFoundException: /local/apollo/var/env/SCoMMockClientWebsite/tomcat/conf/Catalina/localhost/ROOT.xml (No such file or directory)
