现在，我正在做这个EJB教程：http://programming.manessinger.com/tutorials/an-eclipse-glassfish-java-ee-6-tutorial/#heading_toc_j_23，但我使用JBoss 7.0而不是GlassFish，而不是DerbyDB，我使用PostgreSQL和Hibernate作为持久性提供程序。我的问题是，我无法部署EAR并测试web服务（这是我在ATM教程中的位置），因为JBoss给了我以下错误：
ERROR [org.jboss.msc.service.fail] (MSC service thread 1-7) MSC00001: Failed to start service jboss.persistenceunit."JEETutorialEAR.ear/JEETutorialEJB.jar#JEETutorialEJB": org.jboss.msc.service.StartException in service jboss.persistenceunit."JEETutorialEAR.ear/JEETutorialEJB.jar#JEETutorialEJB": Failed to start service

我在项目路径中添加了PostgreSQL JDBC驱动程序。我做了，这里建议的是：http://jan.zawodny.pl/blog/2011/07/jboss-7-postgresql-9没有数据源配置（我想这是由Eclipse在启动服务器期间完成的。）
答案 0 :(得分：1)
您需要手动部署驱动程序，例如在独立模式下将其复制到 $ JBOSS / standalone / deployments /。无需将其打包为模块。
在AS7.1的未来版本中，可以再次使用经典的-ds.xml文件来创建数据源。但这只是一个评论：）
