我使用TomEE部署包含一個EJB JAR和一個WAR的EAR文件。tomee EJB JAR中的persistence.xml META-INF崩潰我的應用程序部署
我想使用默認提供程序添加實體。我在tomee.xml中創建了一個資源來使用MySQL DB。 後來我想用實體管理器，所以我想創建的EJB JAR META-INF目錄下的persistence.xml：
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="MyProjectDataBase" transaction-type="JTA">
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>MyProjectDS</jta-data-source>
<non-jta-data-source>MyProjectDSUnmanaged</non-jta-data-source>
<properties>
<property name="openjpa.jdbc.DBDictionary" value="mysql" />
<property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema" />
</properties>
</persistence-unit>
</persistence>
MyProject的& MyProjectUnmanaged是IDS我tomee.xml創建的資源。
一旦我添加此persistence.xml中我得到了catalina.out的以下異常和我的應用程序未部署：

一旦我刪除的persistence.xml然後應用程序被成功部署。 請幫助我，因爲我不知道如何着手:(提前
感謝。
