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
thought of asking you.waiting for your valuable suggestion and
solutions.Thank you for reading this mail.
I am using windowXP + tomcat5 + jre6+ nutch-0.9
here is the error in the log file (but no error in the browser just a blank
page).
