Are you Jennifer Reese or Jennifer Moran? ;)
What else did you find in your google search. I know I always have a hard time finding hosting companies that have an App Server, and usually when I do they are expensive. Most JSP/Servlet providing hosting companies tend to just give you
Tomcat.
You might have to go get a Virtual machine or private area at the hosting company and install all that stuff yourself.
Good Luck and let us know what you find.
