Hibernate archives can be deployed as top level packages or can be deployed as a component of an EAR file. Since Hibernate archives are not a standard J2EE deployment type, we need to declare them in the jboss-app.xml file of an EAR file to use them that context.
This is done with a module/har element as shown in the following example.
<!DOCTYPE jboss-app PUBLIC "-//JBoss//DTD J2EE Application 1.4//EN" "http://www.jboss.org/j2ee/dtd/jboss-app_4_0.dtd"> <jboss-app> <module> <har>sample.har</har> </module> </jboss-app>
With this, a Hibernate archive can be deployed along side a WAR or EAR file in any EAR file.
