我更改了标题(无法从 EAR 加载持久性单元)，因为我认为问题是，我不能使用“http://xmlns.jcp.org/xml/ns/persistence”网址。相反，我必须使用“http://java.sun.com/xml/ns/persistence”网址。

当我使用“http://xmlns.jcp.org/xml/ns/persistence ”时，出现以下错误:

SEVERE: Unable to load Persistence Unit from EAR: F:\Web Design\wwwroot\Ali Farvardin\Farvardin Workshop\Workshop\build\web, module: file:/F:/Web%20Design/wwwroot/Ali%20Farvardin/Farvardin%20Workshop/Workshop/build/web/WEB-INF/classes/.

它指的是我的 persistence.xml 文件: 
<?xml version="1.0" encoding="UTF-8"?>
<persistence 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" version="2.1">

    <exclude-unlisted-classes>true</exclude-unlisted-classes>
  </persistence-unit>
</persistence>

这是 DD 文件:

<web-app version="3.1" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee  http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd">

</web-app>

和 context.xml: 
<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" path="/Workshop">
    <Resource auth="Container" driverClassName="com.mysql.jdbc.Driver" maxActive="100" maxIdle="30" maxWait="10000" name="jdbc/FarvardinWorkshop" password="don't look, it's a secret" type="javax.sql.DataSource" url="jdbc:mysql://localhost:3306/FarvardinWorkshop" username="root"/>
</Context>

规范:

Web 服务器:Apache TomEE Web Profile 1.7.0

框架:JSF

库:PrimeFaces 5.0、Eclipselink 2.5、Myfaces 2.2.4

平台:JDK 1.8

IDE:Netbeans 8.0

==========================================

考虑到“ http://java.sun.com/xml/ns/persistence”的弃用，我的错误是什么？

提前致谢。

最佳答案

TomEE 目前仅支持 JavaEE 6，而 eclipselink 2.5 是 JPA 2.1，因此是 JavaEE 7。

http://en.wikipedia.org/wiki/Java_EE_version_history

如果您想将 eclipselink 与 tomee 一起使用，您现在应该使用 2.4.2(与 PluME 版本一起打包)。

关于jpa - 使用命名空间，http ://xmlns. jcp.org/xml/ns/persistence/导致错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25625864/
