Indexing a dir recursively and ignoring files

[Issahar (Jus) Weiss]

Hi.
I am trying to use LIUS.
I want to index a directory with its sub-directories, but I want it to ignore certain files, like JPG, SWF and others.
How do I do it?
My code is this:
    String loggerProp = "D:\\Lius-1.0\\Config\\log4j\\log4j.properties";
    String liusCfg = "D:\\Lius-1.0\\Config\\liusConfig.xml";
    String LIUS_IDX = "d:\\liusIdx";
    String toIndex = "d:\\liusDirectory";

    LiusLogger.setLoggerConfigFile(loggerProp);

    LiusConfig lc = LiusConfigBuilder.getSingletonInstance().getLiusConfig(liusCfg);

    LuceneActions.getSingletonInstance().indexSubDirectories(new File(toIndex), LIUS_IDX, lc);

As I understand it, in LuceneActions.fileDirectoryProcessing :
        indexer = IndexerFactory.getIndexer(f, lc);
        if (indexer != null) {
            Document doc = LuceneActions.getSingletonInstance()
                    .populateLuceneDoc(indexer.getPopulatedLiusFields());
            doc.add(new Field("filePath", f.getAbsolutePath(),
                    Field.Store.YES, Field.Index.UN_TOKENIZED));
            iw.addDocument(doc);
        }
if you want to ignore a file, it means that the IndexerFactory.getIndexer(f, lc) should return null for that file.
but if you look into that method:
IndexerFactory.getIndexer:
        try {
            indexer = getIndexer(new FileInputStream(file),MimeTypeUtils.getMimeType(file) , lc);
            indexer.setDocToIndexPath(file.getAbsolutePath());
           
        } catch (FileNotFoundException e) {
            logger.error(e.getMessage());
        }
        return indexer;
if the call for getIndexer will return null, we'll get NullPointerException, which I indeed get.

So, is it a bug, or I just don't know how to ignore files?
thanx very much,
Issahar.

I am searching for the same - How can I exclude some files and folders from searching? Can anybody help?
