我在將Web應用程序部署到最新版本的IBM Websphere 7時遇到問題。 異常是在JPA初始化期間引起的。 應用程序使用的servlet 2.5，的EclipseLink 2.1.3，JAVA 6更新25. 的persistence.xml使用版本1.0將我的JPA應用程序部署到Websphere時出現異常7
我不確定，如果這個異常由錯誤/配置錯誤引起在Websphere或我的應用程序。也許它也與eclipselink有關。
UPDATE
我們的應用程序不使用JNDI提供的數據源來的EclipseLink。我們的應用程序直接傳遞數據源到的EclipseLink（使用特定的EclipseLink EntityManager的屬性）
的的persistence.xml我使用的是（離開了所有的實體定義和調整屬性）：
<?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>
這裏談到的System.err的輸出：

這是至少有效的解決方法。謝謝！ – 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
該設置用於容器管理的JTA（即，JPA提供程序如何與事務服務交互），而不是容器如何與JPA提供程序交互。如果PM26361文檔有助於避免需要容器管理的JPA，那麼在接受答案之前還有什麼需要的嗎？ – 2011-06-09 22:22:29
