Since not all of our clients that order Professional Plans require JSP support, we don't enable it by default. If you want to have JSP enabled on your account please login to your Client Area and submit a support ticket.
After you fill out this form, Tomcat will be enabled on your system between 11:00 pm and 1:00 am Chicago time the same day. We do this, to have as little downtime as possible. Since adding a new Context to Tomcat requires a Tomcat restart and apache restart, we do this during the night, when activity on our servers is at its lowest.
