Nutch Tomcat JasperException

Hi all,
I am a total newb with nutch and tomcat, but I have followed the steps
outlined in http://lucene.apache.org/nutch/tutorial.html#Getting+Started
and was able to get the nutch page to show up when I go to
mydomain:8080. However, my problem is when I run a search. Here is the
following output when I run a search:

HTTP Status 500 - 

________________________________________________________________________

type Exception report

message 

description The server encountered an internal error () that prevented
it from fulfilling this request.

I have no idea what is causing this error. Any ideas. If it makes a
difference I am running this installation on a FC4 box.
Thanks for any insight anyone can provide.
