Installed tomcat and it is running well. But Xwiki wont launch. And unable to find .war file from the downloaded Zip file of LTS Version 17.10.14
I’d suggest to not follow copilot 
And instead to follow the XWiki installation instructions at https://www.xwiki.org/xwiki/bin/view/documentation/xs/admin/installation/
PS: Your message makes little sense since there’s no downloadable zip for Tomcat.
