OpenJPA 2.1.1 - 找不到元素'持久性'的声明

时间:2011-11-29 13:59:13

标签: persistence openjpa persistence.xml

我刚刚下载了http://www.apache.org/dyn/closer.cgi/openejb/4.0.0-beta-1/apache-tomee-1.0.0-beta-1-webprofile.zip以将OpenEJB与OpenJPA2.1.1一起使用。 我无法使我的persistence.xml工作。

堆栈顶部的跟踪:

  

org.xml.sax.SAXException:   文件:/ d:/Workspaces/sandbox/tomcat_ejb_jpa2_tomEE/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/testEE/WEB-INF/classes/META-INF/persistence.xml   [Location:Line:2,C:248]:org.xml.sax.SAXParseException:cvc-elt.1:   找不到元素'持久性'的声明。

我的persistence.xml:

<?xml version="1.0" encoding="UTF-8"?>
<persistence version="2.0" 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_2_0.xsd">
        <persistence-unit name="testEE">
        </persistence-unit>
</persistence>

我已经读过,问题应该通过名称空间声明(xmlns="http://java.sun.com/xml/ns/persistence")来解决,但它仍然不起作用。

答案 0 :(得分:2)

<?xml version="1.0"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    version="2.0">
    <persistence-unit name="jpa-lib">
        <provider>org.apache.openjpa.persistence.PersistenceProviderImpl
        </provider>
        <class>com.dav.jpa.entity.Employee</class>
        <class>com.dav.jpa.entity.Department</class>
        <properties>
            <property name="openjpa.ConnectionURL" value="jdbc:oracle:thin:@localhost:1521:DVD" />
            <property name="openjpa.ConnectionDriverName" value="oracle.jdbc.OracleDriver" />
            <property name="openjpa.ConnectionUserName" value="scott" />
            <property name="openjpa.ConnectionPassword" value="tiger" />
            <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO" />
        </properties>
    </persistence-unit>
</persistence>

这对我有用..

如果稍微简化标记,问题是否会消失?

<?xml version="1.0"?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence" version="2.0">
  ...
</persistence>

我刚刚遇到同样的问题并使用上面的 BUT 修复了它我刚才有了

<persistence version="2.0">

如OpenJpa手册中所示。
