Question

我正在使用TomEE部署一个EAR文件，该文件包含一个EJB JAR和一个WAR。

我想使用默认提供程序添加实体。我在tomee.xml中创建了一个资源来使用MySQL DB。然后我想使用实体管理器，所以我试图在EJB JAR META-INF目录中创建以下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＆amp; MyProjectUnmanaged是我在tomee.xml中创建的资源。

一旦我添加了这个persistence.xml，我在catalina.out中得到以下异常并且我的app没有部署：

删除persistence.xml后，应用程序已成功部署。请帮助我，因为我不明白如何继续:(

提前致谢。

如果您可以指定实际使用的版本，将会很有帮助。

更重要的是，您是否检查过您不会在EAR文件中提供TomEE或任何相关的依赖项（我的意思是lib /或WEB-INF / lib）？

为了您的信息，TomEE 1.5.1将很快发布，并对EAR部署进行一些修复。

EJB JAR中的tomee persistence.xml META-INF崩溃了我的应用程序部署
