Eclipse ejb3.1&；jsf&；JBoss7.1&；靛蓝蚀

我已经开始使用EclipseIndigo+JBoss7.1+MySQL。我是JavaEE的初学者程序员。所以，我对教程有一个问题：。 （这是如何使用MySql数据库的简单示例）

因此，这个项目使用EJB3.1JSF2.0JBoss作为7.1MySQL，当我在控制台中运行这个或类似的项目时，“hibernate”有很多问题

控制台：

O抱歉，当我今天重新启动计算机时，问题似乎消失了。我指的是控制台中的错误。但每次我都有“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）中启动站点时都会被删除。我想启动“SiteMYSQL”。我还有一个问题。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站点占用。我必须更改Tomcat的端口，例如8081

在您的

persistence.xml

中，您有：

    <jta-data-source>jdbc:mysql://localhost:3306/Client</jta-data-source>

在

standalone.xml中：

    <jta-data-source>jdbc/catalogueDS</jta-data-source>

<subsystem xmlns="urn:jboss:domain:datasources:1.0">
    <datasources>
        <datasource jndi-name="java:/jdbc/catalogueDS" pool-name="catalogueDS" enabled="true" use-java-context="true">

jdbc:h2：数据/目录
氢
符合事实的
org.h2.jdbcx.JdbcDataSource

如您所见，
persistence.xml中的
jta数据源
与
standalone.xml中的
jndi名称
匹配。xml
persistence.xml应该放在war的根文件夹META-INF中（对不起，我的英语）
欢迎使用StackOverflow！请向我们展示您正在使用的代码以及它失败的具体位置，以便我们可以帮助您调试问题。请发布您的
persistence.xml
！不，它不起作用。我发现这里有两个问题。首先是数据库，其次我认为显示站点（404）有问题。如果您做了这个更改，与持久性相关的错误会消失吗？或者它们与你第二次发布的内容完全相同？哦，对不起，当我今天重新启动计算机时，问题似乎消失了。我指的是控制台中的错误。但每次我有“HTTP状态404”。欢迎来到这里！对于一年多来没有任何活动的问题，您发布了相同的答案，基本上没有添加任何内容？为什么？因为我也有同样的问题。jboss AS7中的相同日志。在任何论坛上，我都能得到我给出的答案，这就是我的解决方案。我想今天像我这样的人也看到了这个问题。总是说persistence.xml应该放在WEB-INF/classes/META-INF中，而对于JBOSS AS7，如果部署WAR文件时任何不接受/META-INF/persistence.xml的Servlet容器都被破坏（请参阅Servlet规范的第10.6节），则不应这样说。实际上，你应该一直在这里放置这样的东西，而不仅仅是在AS7上。更重要的是，事实证明这不是老年退休金计划的问题。所以你的答案与问题不符。
