java.io.IOException when trying to list terms in index (IndexReader)

[ohaya]

Hi,

I'm starting to work on an app to list all of the terms in the "path" field.  
I'm including the beginning of my code below.

When I run this, pointing it to a directory named "index" containing the Lucene 
indexes, I am getting a java.io.IOException.

Here's the output when I run:

Index in directory :[C:\lucene-devel\lucene-devel\index] was opened 
successfully!
About to drop into while()...
** ERROR **: Exception while stepping through index: [java.io.IOException: The 
handle is invalid]

and here's the code:

import java.io.IOException;

import org.apache.lucene.index.IndexReader;
import org.apache.lucene.index.Term;
import org.apache.lucene.index.TermEnum;


public class ReadIndex {

        public static void main(String[] args) {
                IndexReader reader = null;
                TermEnum termsEnumerator = null;
                Term currentTerm = null;
                
                try {
                        reader = IndexReader.open(args[0]);
                        Term term = new Term("path", "");
                        termsEnumerator = reader.terms(term);
                } catch (IOException e) {
                        System.out.println("** ERROR **: Exception when opened 
IndexReader: [" + e + "]");
                } finally {
                        try { reader.close(); } catch (IOException e) { /* suck 
it up */ }
                }
                
                System.out.println("Index in directory :[" + args[0] + "] was 
opened successfully!");
                
                try {
                        System.out.println("About to drop into while()...");
                        while (termsEnumerator.next()) {
                                System.out.println("About to get 
terms.Enumerator.term()...");
                                currentTerm = termsEnumerator.term();
                                System.out.println("Term = [" + 
currentTerm.text() + "]");
                        }
                        termsEnumerator.close();
                } catch (Exception e) {
                        System.out.println("** ERROR **: Exception while 
stepping through index: [" + e + "]");
                        }
        } // end main()

} // end CLASS ReadIndex

Can anyone tell me what might be causing that exception?

Thanks,
Jim
