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

Question

我正在尝试在 JBoss EAP 6.1 上使用 Kundera 2.5.1(本质上与 JBoss AS 7.1 相同)。但是，当我部署应用程序时，我看到以下异常:

[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

Kundera JAR(核心和 cassandra)部署在我的 EAR 中。有一个 Web 应用程序项目和一个容纳实体的单独的 EJB 项目。 persistence.xml 文件位于 src/META-INF 路径下的 EJB 项目中，但我仍然遇到此异常。我对其他 JPA 提供程序(例如 Hibernate)没有任何问题。

我的 persistence.xml 文件如下所示:

<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>

我错过了什么吗？我的配置看起来还可以吗？或者，这是在 JBoss EAP 6.1 上部署 Kundera 时出现的问题吗？
