私はJavaとJavaEEにかなり慣れていません。プロジェクトに取り組んでおり、JPA（MySQLの場合はhibernate、Cassandraの場合はKundera）を実装する2つのdataSources（MySQL + Cassandra）を使用したいと考えています。私のpersistence.xmlは次のとおりです。

<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    version="2.0">
    <persistence-unit name="mysqlPU" transaction-type="JTA">
        <description>MySQL Persistent Unit</description>
        <jta-data-source>java:jboss/datasources/MySQLRemote</jta-data-source>
    <provider>org.hibernate.ejb.HibernatePersistence</provider>
    <class>com.eventit.entities.Event</class>
    <class>com.eventit.entities.Group_icon</class>
    <class>com.eventit.entities.Group</class>
    <class>com.eventit.entities.User</class> 
    </persistence-unit>
<persistence-unit name="cassandraPU">
    <provider>com.impetus.kundera.KunderaPersistence</provider>
    <properties>
        <property name="kundera.nodes" value="10.0.0.13" />
        <property name="kundera.port" value="9160" />
        <property name="kundera.keyspace" value="KunderaKeyspace" />
        <property name="kundera.dialect" value="cassandra" />
        <property name="kundera.client.lookup.class"
            value="com.impetus.client.cassandra.pelops.PelopsClientFactory" />
        <property name="kundera.cache.provider.class"
            value="com.impetus.kundera.cache.ehcache.EhCacheProvider" />
        <property name="kundera.cache.config.resource" value="/ehcache-test.xml" />
    </properties>
</persistence-unit>

しかし、プロジェクトをJBoss（AS 7.1）にデプロイすると、次のエラーが発生します。

mysqlPUは問題なく動作しますが、cassandraPUを追加すると例外が発生します。http://127.0.0.1:9990/console/App.html#deployments 事前にThanksでjarを確認でき、必要なものをすべて提供できれば、jbossへの依存関係を持つkundera.jarを正しくデプロイしていると確信しています。
