I had that problem yesterday... this works in my app:
Directory directory = new SimpleFSDirectory(new File("c:\\lucene\\index"));
IndexWriter w = new IndexWriter(directory, analyzer,true,
new IndexWriter.MaxFieldLength(25000));

Betreff: Re: index a database
What version are you using? Because there's no such constructor
(i.e. one that takes a File) in 3.0.....
You might want to use something like FSDirectory.open(file) in
your IndexWriter constructor....
If this doesn't work, more details please....
