Question

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”url。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，我会收到以下错误：

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/.

它被称为我的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：

和context.xml：

</Context>

规格：

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

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

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

提前感激。

Answer 1

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

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

如果您想使用eclipselink，请立即使用2.4.2（与PluME版本一起打包）。

Answer 2

有同样的问题，将hibernate更改为旧版本（例如4.1.4 final），显然是最新版本的JPA 2.1 xmlns =＆＃34; http：//java.sun.com/xml/ns/持久性已弃用

Answer 3

我发现了错误。它是持久性版本，我们使用2.1并且Tomee不支持它。因此，转到persistence.xml并删除以下代码

<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">

并添加此

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_2_0.xsd">

有效：）

使用命名空间http://xmlns.jcp.org/xml/ns/persistence/会导致错误
