我已经开始使用 Eclipse Indigo+JBoss 7.1+MySQL。我是 Java EE 的初学者程序员。所以，我对教程有疑问：http ://www.youtube.com/watch?v=z55reyPqH44 。（这是如何使用 MySql 数据库的简单示例）。
所以，这个项目使用：EJB 3.1 JSF 2.0 JBOSS AS 7.1 MySQL，当我在控制台中运行这个或类似的项目时，“休眠”有很多问题。

哦，对不起，当我今天重新启动计算机时，看起来问题丢失了。我的意思是控制台中的错误。但每次我有“HTTP 状态 404”。看看我的控制台和屏幕。我不知道为什么每次 JBoss 从我的旧项目（CountryWebService）中启动站点被删除。我想启动'SiteMYSQL'。我还有另一个问题。当我删除我的 JBoss 7.1 服务器并启动新的 Tomcat 7 时，我的端口 8080 每次都被 JBoss 站点忙碌。我必须更改 Tomcat 的端口，例如 8081。
