Hibernate Search into a JBoss AS7 Cluster

[petrussello]

Hello,

I'm developing a Seam 2.3.1 application that runs on a JBoss AS7 Cluster configured following the official tutorial.

My question is 'How to configure the persistence.xml file to obtain a replicated index in every node of the cluster?'

Hibernate Search says that there are 2 approaches using jgroups backend:

1. Master-Slaves backend with different persistence.xml configurations for every node.
2. Automatic Master election

I don't know how to realize the first solution because I don't know how to deploy different myapplication.war archive files for the nodes (I'm deploying the application from the apposite panel 'Manage Deployments' in the admin console).

I don't even know how to realize the second solution because I didn't understand how to configure the persistence.xml to do the trick,

I have tried with this persistence.xml file (I only added the red row to my original file):

<?xml version="1.0" encoding="UTF-8"?>

<!-- Persistence deployment descriptor for dev profile -->

<persistence 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_2_0.xsd"

             version="2.0">

  <persistence-unit name="myApplication" transaction-type="JTA">

   <provider>org.hibernate.ejb.HibernatePersistence</provider>

   <jta-data-source>java:jboss/datasources/MySqlXADS</jta-data-source>

   <properties>

     <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>

     <property name="hibernate.hbm2ddl.auto" value="update"/>

     <property name="hibernate.show_sql" value="false"/>

     <property name="hibernate.format_sql" value="true"/>

     <property name="hibernate.default_catalog" value="myapplication"/>

     <property name="jboss.entity.manager.factory.jndi.name" value="java:/myApplicationEntityManagerFactory"/>

     <property name="hibernate.search.default.directory_provider" value="filesystem"/>

     <property name="hibernate.search.default.indexBase" value="/HibernateSearchIndexFolder"/>

             <property name="hibernate.search.default.worker.backend" value="jgroups"/>

     <property name="hibernate.search.indexing_strategy" value="manual"/>

    </properties>

  </persistence-unit>   

</persistence>

I hope someone can help me.

Thanks
