I spoke a little too quickly, ServletContext is avilable from ctx
(just didn't search hard enough).  Adding the request listener here

java.lang.NullPointerException

org.apache.catalina.core.ApplicationContext.createListener(ApplicationContext.java:1402)

        at 
org.apache.catalina.core.ApplicationContext.addListener(ApplicationContext.java:1307)

org.apache.catalina.core.ApplicationContextFacade.addListener(ApplicationContextFacade.java:636)
