nutch-0.8.0-dev search error

I successfully ran the intranet crawl and my nutch/crawl dir was 
generated. I then deployed the war file and stopped/started tomcat from 
within the crawl directory. However, when I attempt to actually run a 
search, a page with the following error is returned. Any ideas?

It seems that some classes cannot be found. Have you set up the Java CLASSPATH 
correctly in your environment resp. start script? Does it contain rt.jar? The 
complete log should tell you which class is missing. That helps you to find 
out which lib is not in the correct Java search path.
