我尝试在 OSGI 平台上部署一个项目，其中 EclipseLink JPA 用作 ORM 工具。该项目在 OSGI 容器之外运行时运行良好。

使用版本：Spring 2.5.6、EclipseLink 1.2.0

不幸的是，我在 OSGI 平台上收到此错误：

Exception Description: Unable to acquire a connection from driver [null], user [null] and URL [null].  Verify that you have set the expected driver class and URL.  Check your login, persistence.xml or sessions.xml resource.  The jdbc.driver property should be set to a class that is compatible with your database platform

由于未知原因，EclipseLink 未检索到创建并添加到 org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean 的数据源

欢迎任何想法？

亲切的问候，

看，

确保您的 DataSource 是可访问的，并且您的所有 OSGi 和 Spring 配置都是正确的。

您是否检查过数据库属性文件是否在类路径中？

确保它在那里。
