Nutch on Windows

[Top 100 Forever <to...@top100forever.com>]

Hi to all,
I'm a new user of nutch. I would like to study it's architecture,
but for the first time I have available only a windows machine.
I have read that this is not a problem. Nutch is written in java 
and so it have to work on all platforms...

So I'm trying to install it on this machine:
- java jdk 1.5.0
- tomcat 5.5.9
- nutch 0.7.1
- win XP

I have read the tutorial and the guide GettingNutchRunningWithWindows.
But with both type of installation, i have all the time the same problem: 
When i try lo load the page: http://localhost:8080/ i receive a black page
and tomcat log appear as the follow:

...............................................
- Server startup in 3297 ms
- Exception initializing page context
java.lang.StackOverflowError

 at javax.servlet.http.HttpServletRequestWrapper.getSession(HttpServletRequestWrapper.java:215)
 at org.apache.catalina.core.ApplicationHttpRequest.getSession(ApplicationHttpRequest.java:544)

Could you kindly help me to solve this problem?
Thanks in advance
