I was getting null when I called getServletContextName(), since I forgot
to define <display-name> in my web.xml. After I added it, I see
contextInitialized(event) being called twice.

yeah, I could go with a servlet, but I'd rather go with
ServletContextListener approach, since it should work. The sentence is
was worded a bit awkward. Basically I will have multple webapps running
in Tomcat. I want to make sure that each webapp loads it's particular
application.

going with the servlet approach does provide more control, but it would
be nice to use the context listener method. I'm guessing it's a bug
with tomcat, since I do get two ContextInitialized(event) events beign
fired.
