Re: Can't start Lucene App: java.io.FileNotFoundException with brand new directory

Hi,
I think you should use another IndexWriter constructor:

IndexWriter(Directory d, Analyzer a, IndexWriter.MaxFieldLength mfl)
          Constructs an IndexWriter for the index in d, first *creating it
if it does not already exist*.

Hope this helps.
Bye
