Hi, I'm desperately trying to replace the current architecture with a master/slave architecture via JMS. The future goal is to have the master running on another machine. However, for the first approach it's fine having the master running on the very same machine.
I'm using
- Tomcat7
- Hibernate 4.3.7
- Hibernate Search 5.0.1.FINAL
- ActiveMQ 5.10
The already existing implementation should be converted as slave. After studying the documentation, I ended up with the following approach to the configuration:
Code:
<!-- Hibernate search configuration -->
<!-- remote and local location of indexes -->
<property name="hibernate.search.default.sourceBase" value="/home/neven/lucene/master" />
<property name="hibernate.search.default.indexBase" value="/home/neven/lucene/indexes" />
<!-- Copy remote index to local index every 10 minutes -->
<property name="hibernate.search.default.refresh" value="600" />
<!-- Directory provider -->
<property name="hibernate.search.default.directory_provider" value="org.hibernate.search.store.impl.FSSlaveDirectoryProvider" />
<!-- JMS backend configuration -->
<property name="hibernate.search.worker.backend" value="jms" />
<property name="hibernate.search.worker.jms.connection_factory" value="tcp://localhost:61616?trace=true" />
<property name="hibernate.search.worker.jms.queue" value="hibernateSearchQueue" />
(Note: the sourceBase and indexBase directories are empty, yet)
When I try to initialize the EntityManagerFactory, the following stracktrace is produced:

When I revert the changes to the persitence.xml config file (before trying to use JMS), the test runs successfully.
Any ideas or links to a good tutorial (that describes the transition to a master/slave architecture using JMS)?
Thanks!
