Hello Ashumeet,
Yes, thats a symptom of malformed XML, if you haven't change the nutch-
default.xml file, then its probably the version of the SAX parser you
are using. Which version of Java are you using...?
Best regards,

I am not sure which tag is missing in nutch-default.xml. Also
"Content is not allowed in prolog." I don't understand what is it
trying to say. I can view it in the browser but the search is empty
because there is no crawl happened till now.
Thanks for the prompt reply.

Hey everyone…!!! I am pleased to be a part of this community. I am a
student trying to learn nutch. I have installed nutch and tomcat
properly.
And they are running but at the time of crawl, when I am running the
following command in terminal:
./nutch crawl urls -dir crawl -depth 3 -topN 50
It is giving me the following error:
