I had the same problem before. Just read http://www.mail-archive.com/nutch-dev%40lucene.apache.org/msg04303.html
Make that tiny change on line 385 of HttpBase.java and it will work fine. Raphael Sellek, Greg wrote:
I am experiencing the same issue as a similar post for 8/6. Whenever I try and fetch pages, I see a lot of "fetch of xxx failed with: java.lang.NullPointerException" I have put the appropriate agent info in both the nutch-default and nutch-site config files. I tried using DEBUG logging to get more info, but this error is the extent of what I see. Seems to happen on about 95% of the urls I am trying to crawl. BTW, this happens with both the 0.8 build and the latest nightly build. TIA for any advice as to what I am doing wrong. Greg
