There are issues with putting the Spark web UI behind JSP - there's a (long) discussion on #57. At a minimum you need to configure Spark to tell it that it's being accessed through a proxy, but it looks like there's also a bug in Spark itself when the URL contains the word Proxy (apache/spark#31774 ).

Unfortunately, I don't think there's anything JSP itself can do here - the config and/or fixes are needed on the Spark side to cope with being accessed via a reverse proxy.
