我正在使用 Hibernate 从 Karaf 2.3.4 容器连接到 PostgreSQL，当我部署我的包时，出现一个异常说 javax.naming.NameNotFoundException osgi:service/javax.sql.DataSource/"(osgi.jndi.service.名称=jdbc/postgresds）。

我解决了这个问题，并按照 M. Cristian 的说法更新了文件列表，但这是另一个奇怪的问题：重新启动 Karaf 并尝试通过 Karaf 控制台插入数据时，控制台打印：The is no active Transaction，所以我尝试了使用 EntityManager 的其他方式，问题不再出现。
