That is the common case, other being there is no data available.
I have started tomcat in the nutch directory.
I have also added a preference to nutch:

<property>
  <name>searcher.dir</name>
  <value>crawl</value>
  <description>
  Path to root of crawl.  This directory is searched (in
  order) for either the file search-servers.txt, containing a list of
  distributed search servers, or the directory "index" containing
  merged indexes, or the directory "segments" containing segment
  indexes.
  </description>
</property>


Any other steps to take?
  

No, that should do it. Couple of things you can try:

- double check that your configuration is indeed in use the file to 
check is in ${webapps}/ROOT/WEB-INF/classes/nutch-site.xml
- use absolute directory in searcher.dir, that way it does not matter 
where or how you start tomcat.

you can also check that you can actually get results back from nutch 
command line:
- double check $nutch-home/conf/nutch-site.xml (searcher.dir)
- execute (from command line) bin/nutch 
org.apache.nutch.searcher.NutchBean <query>

Hi,

I just dropped Nutch web app into tomcat version 6.0.18 and it worked 
fine, perhaps you should upgrade your Tomcat?

Hi,

I am following the tutorial here: 

http://nutch.sourceforge.net/docs/en/tutorial.html

Crawling works fine, as does the test search from the command line. When 
    

  
I try to fire up tomcat after moving ROOT.war into place, I get some 
errors in the tomcat logs and a page with

So it looks like the root of the error is default web.xml, not in the 
Log4JLogger - although I know very little about Java.  I haven't played 
with it for a few years.

Anyone know what is going on here?
