It's something broken in Lucee. If start Lucee fresh with code located in vhost folder - it says Application.cfc not found (while it's obviously there and not included into any file). But if start Lucee clean with EMPTY vhost folder, it creates WEB-INF folder in that vhost folder, then I copied website files to this folder - first Application.cfc - ok, index.cfm - ok, then other cfms and custom tags, last - css js. Works! So what was the reason why Lucee created some kind of broken context when folder wasn't empty - I can only guess, but I will find out when have time.
