事先，我为这篇冗长的帖子道歉，但这个问题有很多细节：

我开始在尝试运行Java EE应用程序时收到以下错误：

 SEVERE: Unable to load Persistence Unit from EAR: E:\workspace-sts\.metadata\.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\CAT, module: file:/E:/workspace-sts/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/CAT/WEB-INF/classes/. Exception: unexpected element (uri:"http://xmlns.jcp.org/xml/ns/persistence", local:"persistence"). Expected elements are <{http://java.sun.com/xml/ns/persistence}persistence>
 javax.xml.bind.UnmarshalException: unexpected element (uri:"http://xmlns.jcp.org/xml/ns/persistence", local:"persistence"). Expected elements are <{http://java.sun.com/xml/ns/persistence}persistence>

这似乎指向我的persistance.xml文件：

 <persistence
    version="2.1"
    xmlns="http://xmlns.jcp.org/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/persistence http://xmlns.jcp.org/xml/ns/persistence/persistence_2_1.xsd">

所以，我把它改为：

 <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

错误消失但后来被替换为：

 SEVERE: Unable to deploy collapsed ear in war StandardEngine[Catalina].StandardHost[localhost].StandardContext[/dally]
 org.apache.openejb.OpenEJBException: Unable to load servlet listener class: sdc.cdd.dally.AppListener: sdc.cdd.dally.AppListener

现在我被卡住了。在此先感谢您的帮助。

BTW，这是基本的应用程序架构：

JDK 1.7
STS 3.4
Tomcat 7
Apache Tiles
EclipseLink 2.5.0 - 开普勒（JPA）

我还包含了pom.xml。

完整的堆栈跟踪会有所帮助。

但是，您的第一个persistence元素声明是正确的，而第二个元素已被弃用。

并且错误似乎与OpenEJB相关联。也许你把它作为瞬态依赖，并引用旧版本，但这只是一个假设。

另一件事是您正在使用javax.inject并且我不确定它在Tomcat上是否可用独立。

你应该使用功能齐全的应用服务器（glassfish，jboss，也许是TomEE）而不是增强型Tomcat，它虽然是一个 servlet容器，但要避免这些兼容性问题。
