将JPA应用程序部署到Websphere 7时出现异常

我在将Web应用程序部署到最新版本的 IBM Websphere 7 时遇到问题 . exception 是在JPA初始化期间引起的 . 该应用程序使用 servlet 2.5, eclipselink 2.1.3 ，java 6更新25. persistence.xml使用的是1.0版

我是 unsure ，如果此异常是由 bug/configuration error in Websphere 或我的应用程序引起的 . 也许它也与eclipselink有关 .

UPDATE

我们的应用程序不使用JNDI为EclipseLink提供数据源 . 我们的应用程序将DataSource直接传递给EclipseLink（使用EclipseLink特定的EntityManager属性）

我正在使用 persistence.xml （省略所有实体定义和调优属性）：

<?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>

这是 System.err 输出：
