Subject Java error crawling
Date Thu, 21 Feb 2008 10:26:34 GMT

Hi everybody,
I have a problem.
I have to crawl a site made with java/jsf using myfaces. The servlet
container is Tomcat 6.
When I'm crawling the site, some pages generates this java error:

GRAVE: Servlet.service() for servlet jsp threw exception
