Kundera（JPA）-在类路径中找不到任何META-INF / persistence.xml文件

Question

I am trying to play around with Kundera 2.5.1 on JBoss EAP 6.1 (essentially the same as JBoss AS 7.1). However, when I deploy my application, I see the following Exception:

[0m[31m12:44:24,119 ERROR org.jboss.msc.service.fail MSC000001: Failed to start service jboss.persistenceunit."KunderaTests-ear.ear/KunderaTests-ejb.jar#KunderaTests": org.jboss.msc.service.StartException in service jboss.persistenceunit."KunderaTests-ear.ear/KunderaTests-ejb.jar#KunderaTests": com.impetus.kundera.loader.PersistenceLoaderException: com.impetus.kundera.utils.InvalidConfigurationException: Could not find any META-INF/persistence.xml file in the classpath

The Kundera JARs (core & cassandra) are deployed within my EAR. There is a Web application project, and a separate EJB project that houses the entities. The persistence.xml file is in the EJB project under the src/META-INF path, but I still get this exception. I do not have any problems with other JPA providers, such as Hibernate.

My persistence.xml file looks like this:

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

    <persistence-unit name="KunderaTests">
        <provider>com.impetus.kundera.KunderaPersistence</provider>
        <properties>
            <property name="kundera.nodes" value="localhost" />
            <property name="kundera.port" value="9160" />
            <property name="kundera.keyspace" value="dev" />
            <property name="kundera.dialect" value="cassandra" />
            <property name="kundera.client.lookup.class"
                value="com.impetus.client.cassandra.pelops.PelopsClientFactory" />
        </properties>
    </persistence-unit>
</persistence>

Am I missing something? Does my configuration look okay? Or, is this an issue with deploying Kundera on JBoss EAP 6.1?
