Hi Folks,
I am following the Nutch tutorial
http://lucene.apache.org/nutch/tutorial.html and trying to install
Nutch-0.7.2 on Ubuntu. I have also seen the wiki entry for getting
Nutch running on Ubuntu and followed all the steps.
The search works fine if I give the command:
bin/nutch org.apache.nutch.searcher.NutchBean query
If I access it via the browser I get the following error when I
search. The below error is for opensearch, but the searching using
search.jsp also gives a similar error.
I have edited the nutch-site.xml properly to point searcher.dir to the
right place.
Please help.
