Estoy implementando una aplicación Hibernate (v 4.1.5.SP1, validator 4.3.0.Final) (a Archivo Jar) ejecutándose en MySQL 5.5 db a JBoss 4.2.3.GA (no puede cambiar esto). Recibo el error "org.hibernate.cache.NoCachingEnabledException: la memoria caché de segundo nivel no está habilitada para el uso" cuando se ejecuta la aplicación, pero parece que configuré todo correctamente. Estoy usando estas dependencias Maven ...Problemas para configurar la memoria caché de Hibernate - org.hibernate.cache.NoCachingEnabledException: la memoria caché de segundo nivel no está habilitada para el uso
<!-- Hibernate dependencies -->
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>${hibernate.validator.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>

<version>${hibernate.version}</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-ehcache</artifactId>
<version>${hibernate.version}</version>
</dependency>
El error es extraño porque tengo la caché configurado en mi archivo hibernate.cfg.xml ...
<?xml version='1.0' encoding='utf-8'?>

esto está incluido en mi archivo META-INF/persistence.xml, que está por debajo ...

<property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
</properties>
</persistence-unit>
</persistence>
Para anular los cargadores de clases de JBoss, que incluyen el archivo de META-INF/jboss.xml ...
<jboss>
<class-loading java2ClassLoadingCompliance="false">
<!-- setup classLoader repository. java2ParentDelegation to always have
package libs override server libs for this application -->
<loader-repository>
org.mainco.subco.orgs:loader=orgsclient
<loader-repository-config>
java2ParentDelegation=false
</loader-repository-config>
</loader-repository>
</class-loading>
</jboss>
Aquí está el seguimiento completo de la pila. ¿Cuál es la causa de esto?

es 'hibernate.cache.provider_class 'definido como' org.hibernate.cache.EhCacheProvider'? – SiB
