Openshift - 没有EntityManager的持久性提供者

我在将应用程序部署到Openshift.com时遇到问题。Openshift - 没有EntityManager的持久性提供者

我想在Tomcat上创建简单的Java JPA应用程序。应用程序在本地启动，但是当我把它部署到Openshift.com我有这样的错误：

javax.persistence.PersistenceException: 
No Persistence provider for EntityManager named testpersist

您正在使用不在类路径中的EclipseLink提供程序。你需要以下添加到您的pom.xml文件：

<dependency> 
    <groupId>org.eclipse.persistence</groupId> 
    <artifactId>org.eclipse.persistence.jpa</artifactId> 
    <version>2.5.1-RC3</version> 
</dependency>

我用同样的问题挣扎，发现META-INF必须在src /主/资源，而不是的src/main/java来加载persistence.xml。
