Tomcat Param / Railo issue
If you come across this error in your Tomcat logs:
ServletException: static path [/WEB-INF/railo] for servlet init param [railo-web-directory] is not allowed, path must use a web-context specific placeholder.
Open up your web.xml and change:
<param-value>/WEB-INF/railo</param-value>
To:
<param-value>{web-root-directory}/WEB-INF/railo</param-value>
It should fix it.
