Hello,
I have a similar problem. Here is my persistence.xml:
Code:
<?xml version="1.0" encoding="UTF-8"?>
<!-- Persistence deployment descriptor for dev profile -->
<persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
<persistence-unit name="ulbapps">

<property name="hibernate.search.autoregister_listeners" value="true"/>

<property name="hibernate.search.default.indexBase" value="/home/gressho/lucene"/>
</properties>
</persistence-unit>
</persistence>
The indexBase is in my home dir and JBoss runs with my user id, so it
should be writable. My environment is a JBoss AS 4.2.2 (with original
hibernate and hibernate annotations in server/default/lib) which
runs on JDK 1.5 update 15 on a linux machine. My application is an
EJB3 application, so the transactions start in a stateless session bean:
Code:
public void save(ItemVO itemVO) {
if (itemVO.getId() == 0) {
Item item = new Item();
item.setContent(itemVO.getContent());
Context context = em.find(
Context.class, itemVO.getContext().getId());
context.getItems().add(item);
item.setContext(context);
for (DescriptionVO descriptionVO : itemVO.getDescriptions()) {
if (descriptionVO.getDescription().length() > 0) {
Description description = new Description();
description.setDescription(descriptionVO.getDescription());
description.setItem(item);
item.getDescriptions().add(description);
}
}
for (UrlVO urlVO : itemVO.getUrls()) {
if (urlVO.getUrl().length() > 0) {
Url url = new Url();
url.setUrl(urlVO.getUrl());
url.setDescription(urlVO.getDescription());
url.setItem(item);
item.getUrls().add(url);
}
}
item.setTimeChanged(itemVO.getTimeChanged());
item.setTimeCreated(new Date());
item.setTimeExpired(itemVO.getTimeExpired());
em.persist(item);
} else {
Item item = em.find(Item.class, itemVO.getId());
for (Iterator<Description> iterator =
item.getDescriptions().iterator();
iterator.hasNext(); ) {
Description description = iterator.next();
iterator.remove();
em.remove(description);
}
for (DescriptionVO descriptionVO : itemVO.getDescriptions()) {
if (descriptionVO.getDescription().length() > 0) {
Description description = new Description();
description.setDescription(descriptionVO.getDescription());
description.setItem(item);
item.getDescriptions().add(description);
}
}
for (Iterator<Url> iterator =
item.getUrls().iterator();
iterator.hasNext(); ) {
Url url = iterator.next();
iterator.remove();
em.remove(url);
}
for (UrlVO urlVO : itemVO.getUrls()) {
if (urlVO.getUrl().length() > 0) {
Url url = new Url();
url.setUrl(urlVO.getUrl());
url.setDescription(urlVO.getDescription());
url.setItem(item);
item.getUrls().add(url);
}
}
item.setContent(itemVO.getContent());
item.setTimeChanged(new Date());
item.setTimeExpired(itemVO.getTimeExpired());
em.merge(item);
}
}
which uses the entity bean

The result is: the directory /home/gressho/lucene/indexes/si stays
empty either after an persist or a merge.
I'm using hibernate-search 3.0.1.GA and hibernate-commons-annotations-3.0.0.ga and lucene 2.3.0
(additionaly to the provided hibernate 3.2.4.SP1 from JBoss)
Best wishes
