I have worked with database and servers in the past (like um 15 years ago?), so everything is familiar, if not exactly making sense to me.
I have installed both Liferay and Alfresco, which both use Tomcat. Both stacks are giving me the same error when I try to launch the application:
HTTP Status 404 - /
type Status report
description The requested resource is not available.
I know this seems like such a simple thing, but any assistance in getting past this point would be appreciated.
