[hibernate-dev] HSearch + Tika bridge using Wildfly modules

[Brett Meyer]

Sanne, I might still be missing something.  Artificer's war does not include any Hibernate ORM, Hibernate Search, or Tika jars.  For Wildfly 8.2, the war's jboss-deployment-structure.xml includes:

<module name="org.hibernate.search.orm" /> (includes tika-parsers-1.6.jar)
<module name="org.apache.tika" slot="1.6"/>
(Also using the org.hibernate module, but that's implicitly added by Wildfly.)

I understand what you're saying about the ORM classloader, but the above still didn't work.  I'm admittedly a little fuzzy on WF module classloading, but I'm wondering if that's not actually making its way into the ORM classloader, even though my war is the persistence unit.

However:

What *does* work is adding '<module name="org.apache.tika" slot="1.6"/>' directly in org.hibernate.search.engine's module.xml.

Apologies if 1.) I'm missing something and/or 2.) that's expected.  I can certainly tweak org.hibernate.search.engine's module.xml with our installer, but that's obviously less than desirable.  Any idea what we might be missing that would allow us to get that to work from the app itself?

Thanks for the help!
