I installed Nutch the past days, and I kept getting blank results pages at http://localhost:8080/search.jsp... Tomcat was properly installed, I think,
so I looked further and I found that everytime I run a crawl, I get
this toward the end:


060621 125637 indexing segment: crawl.test/segments/20060620163405
Exception in thread "main" java.lang.IllegalAccessError: tried to access field org.apache.lucene.index.IndexWriter.mergeFactor from class org.apache.nutch.indexer.IndexSegment at org.apache.nutch.indexer.IndexSegment.indexPages(IndexSegment.java:102) at org.apache.nutch.indexer.IndexSegment.main(IndexSegment.java:263)

In case the above happens to anyone else, don't be an idiot like I was and
have newer versions of lucene-core lying around; I had installed lucene-core-2.0.0.jar before installing nutch, which comes with lucene-core-1.9.1.jar, and 2.0.0 was being used rather than 1.9.1 - some class definitions in the newer version are different
I guess.

Cheers,
Mike
