Hibernate 3.6 issue with JBoss EAP 6.1.0 Final
We have several applications deploys on JBoss AS, and each uses different version of hibernate.
Therefore, we created several slot for hibernate under modules
- <JBOSS_HOME>/home/com/company/3party/hibernate/main (version 3.0)
- <JBOSS_HOME>/home/com/company/3party/hibernate/3.2
- <JBOSS_HOME>/home/com/company/3party/hibernate/3.6
One of the application contains EJB that uses JPA and Hibernate 3.6, and we did the following declaration:
1) Declare exclusions of JBoss AS hibernate and JPA + include Hibernate 3.6 module dependency in EAR's jboss-deployment-descriptor.xml
<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.2">
<ear-subdeployments-isolated>false</ear-subdeployments-isolated>
<deployment>
<exclusions>
<module name="org.hibernate"/>
<module name="org.jboss.as.jpa"/>
...
</exclusions>
<dependencies>
<module name="com.company.3party.hibernate" slot="3.6"/>
...
</dependencies>
</deployment>
<sub-deployment name="inspect-ejb.jar">
<exclusions>
<module name="org.hibernate"/>
<module name="org.jboss.as.jpa"/>
...
</exclusions>
<dependencies>
<module name="com.company.3party.hibernate" slot="3.6"/>
</dependencies>
</sub-deployment>
</jboss-deployment-structure>
2) Under EJB's persistence.xml, declare provideModule and disable 2nd cache
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

...
<mapping-file>META-INF/orm.xml</mapping-file>
<properties>

<!-- <property name="jboss.as.jpa.providerModule" value="com.company.company.hibernate:3.6" /> This did not work so commented out -->
<property name="jboss.as.jpa.providerModule" value="hibernate3-bundled" />
</properties>
</persistence-unit>
</persistence>
3) I disabled infinitspan sub-system (I uses standalone full profile) because I see that uses Hiberante 4.
I want to avoid any protential class loading issue.
When I start up JBoss AS to deploy the EAR, I see that:

To me it seems like the default JBoss hibernate and JPA always gets loaded, even though we included the exclusions declaration in our deployment descriptor. That causes class loader to ignore the Hibernate 3.6 module we defined.
Please help as I do not know what I have missed. Many thanks in advance!!
