在我的Eclipse动态Web项目中，我使用JPA。我已经在TomEE服务器下的tomee.xml中创建了连接，并且工作正常。我创建了一个persistence.xml文件，如下所示；但是，如果尝试在我的BusinessBean中添加@PersistenceContext（unitName =“ myPersistence”）行，则会看到以下错误，并且服务器无法启动。如果尝试在unitName下插入一个随机名称，也会看到相同的错误。很奇怪，我该如何解决问题？谢谢！
我的持久性文件：
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="1.0">
<persistence-unit name="myPersistence">
<jta-data-source>connessioneCorsoWeb</jta-data-source>
<properties>
<property name="openejb.jpa.auto-scan" value="true" />
<!-- <property name="openjpa.jdbc.SynchronizeMappings" value="buildSchema(ForeignKeys=true)" /> -->
</properties>
</persistence-unit>
</persistence>
我的错误：

答案 0 :(得分：0)
注入的上下文（business.PersonaBean/erisci）是什么类型？必须为EntityManager。如果需要EntityManagerFactory，请使用@PersistenceUnit。如果是EntityManager，则可能意味着您的应用打包了一个与提供的jpa api冲突的jpa api。
