Blank result page

[balachanthar palanivelu <ba...@gmail.com>]

Dear nutch users


. I have some problem with nutch result some times it gives me blank page
without any error but when i see the log file i got some error. I don't
understand how to solve it i tried all the ways up to my extend. So i though
of asking you.

I am using fedora 6 + tomcat5 + jre6+ nutch-0.8.1


here is the error in the log file (but no error in the browser just a blank
page).


ERROR [jsp] - Servlet.service() for servlet jsp threw exception
java.lang.NullPointerException
