我在将Web应用程序部署到最新版本的IBM Websphere 7时遇到问题。 异常是在JPA初始化期间引起的。 应用程序使用的servlet 2.5，的EclipseLink 2.1.3，JAVA 6更新25. 的persistence.xml使用版本1.0将我的JPA应用程序部署到Websphere时出现异常7
我不确定，如果这个异常由错误/配置错误引起在Websphere或我的应用程序。也许它也与eclipselink有关。
UPDATE
我们的应用程序不使用JNDI提供的数据源来的EclipseLink。我们的应用程序直接传递数据源到的EclipseLink（使用特定的EclipseLink EntityManager的属性）
的的persistence.xml我使用的是（离开了所有的实体定义和调整属性）：
<?xml version="1.0" encoding="UTF-8"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<non-jta-data-source></non-jta-data-source>
<class>my.applications.entity.classes.A</class>
<!-- other class definitions follow -->
<properties>
<property name="eclipselink.logging.level" value="FINEST" />
<!-- some other properties, not related to datasources/connections/JNDI
follow -->
</properties>
</persistence-unit>
</persistence>
这里谈到的System.err的输出：
com.ibm.ws.exception.RuntimeWarning: com.ibm.ws.metadata.MetaDataException: CWWJP0018E: Incorrect syntax or error detected in /path/to/my/project/my_application_war.ear/my_application.war/WEB-INF/classes/ for application my_application_war module my_application.war.

这是至少有效的解决方法。谢谢！ – MRalwasser 2011-06-09 14:17:50
我不想使用容器管理的JPA。我正在使用RESOURCE_LOCAL。 – MRalwasser 2011-06-09 17:15:45
该设置用于容器管理的JTA（即，JPA提供程序如何与事务服务交互），而不是容器如何与JPA提供程序交互。如果PM26361文档有助于避免需要容器管理的JPA，那么在接受答案之前还有什么需要的吗？ – 2011-06-09 22:22:29
