Index all the files in a directory

P.S.

if you're not using 1.5......

Dear Erick (and everyone who might read my post) hi and
thank you very much
for your help.
I've tried your program but I do something wrong and it is
only index the
last txt in the directory. If you could see my problem
because I am new to
Java and Lucene as well. 
Thanks in advance

Kostas


public void parseAll() throws Exception {
            String sParentDir = "/database";

        indexTree(new File(sParentDir));
        }

        if (file.isDirectory()) {
        String[] files = file.list();

        for (int idx = 0; idx < files.length; idx++) {
        indexTree(new File(file, files[idx]));
        }
        }
        } else {
        if
(file.getName().toLowerCase().indexOf(".txt") ==
-1)

                               InputStreamReader(fis)));

                writer.addDocument(doc);
                writer.optimize();
                fis.close();
            
            writer.close();

    } catch (IOException ioe) {
            System.out.println(ioe);

        }
        }
        }
        }

You are opening a new overwriting IndexWriter for every
file, so only  
the last one is indexed.  You should open your IndexWriter
outside  
the loop and close it afterwards.
