Hi, I have been playing with your test archive. The easiest way I had to get it to work is to:

• remove the dependency to hibernate-search-infinispan (even if you want to use it, you don't need to explicitly add it as we'll inject it with the next steps)
• declare hibernate-search-orm as "provided": you don't want to include it nor any of its dependencies in your EAR.
• downloaded and installed the JBoss Modules we created; this is a set of pre-made and tested dependencies specifically for AS7. You can get them from: https://repository.jboss.org/nexus/service/local/repositories/releases/content/org/hibernate/hibernate-search-modules/4.2.0.Final/hibernate-search-modules-4.2.0.Final-jbossas-71-dist.zip
• you just add a line to your HibernateSearchTest-ear-1.0/META-INF/MANIFEST.MF:

Dependencies: org.hibernate.search.orm services

This will have your application get the modules it needs without any conflict, and we have integration tests for this configuration so you don't have to lose your mind on dependencies

You can also have Maven download and install it for you, I wrote more about this on the blog:
