Greetings,
Problem: Update index.
This code works with lucene-1.2 however throws io.Exception 'Lock time out
' with the lucene-1.3-final version. Any ideas what I might be missing?
Thank you,

Steps taken to update the index.
(i) Open the reader, find the Document with the given term and delete the
term.
(ii) Open Writer and the new term.
<code>
public synchronized void updateProductIndex(String[] keys) throws
Exception {
ContentFactory contentFactory = getFactory("ml.product");
ProductDocumentBuilder documentBuilder = (ProductDocumentBuilder)
getBuilder("ml.product");
final String keysToString = "[ " + StringUtils.join(keys, " , ") +
" ]";
logger.info("index() rebuilding for " + keysToString);
logger.info(" loaded data, indexing");
long start = System.currentTimeMillis();
Iterator items = contentFactory.contentIterate(keys);
// Open the deploy directory to check it contains a document for
the product.
IndexReader reader = IndexReader.open(deployDir);
List documentsList = new ArrayList();
while (items.hasNext()) {
SearchProduct product = (SearchProduct) items.next();
TermDocs terms = reader.termDocs(new
Term(DocBuilderConsts.PRODUCT_ID,
product.getPK().toString()));
// find the documents for the given product ID delete it and
then add it to the index.
// There should only be one document per product in the index.
if (terms.next()) {
logger.info("indexProducts() removing product:" +
product.getPK().toString());
try {
reader.delete(terms.doc());
} catch (IOException e) {
logger.error("Failed to delete product:" +
product.getPK().toString(), e);
throw new Exception("Failed to delete product:" +
product.getPK().toString() + e.toString());
}
}
// write and reader cannot be open at the same time! so add
the document to a temp list;
documentsList.add(documentBuilder.getDocument(product));
}
// make sure to close the reader. Can't have the reader and writer
onen on the same index concurrently!
//close this IndexReader, to flush deletions
reader.close();
reader =null;
if (documentsList.size() > 0) {
/*create the indexer make to sure to pass param 'create' as
false; don NOT want to create a new index replacing the
existing index!*/
IndexWriter writer = new IndexWriter(deployDir, new
StandardAnalyzer(), false);
writer.mergeFactor = mergeFactor;
for (int i = 0, j = documentsList.size(); i < j; i++) {
Document document = (Document) documentsList.get(i);
writer.addDocument(document);
}
writer.optimize();
writer.close();
writer =null;
}
logger.info(" indexer took " + (System.currentTimeMillis() -
start) + " (ms) " + " to rebuild products with ids = " +
keysToString);
contentFactory.flush();
}
