在 JBOSS 中，PersistenceUnit 的预部署失败，带有 toplink 要点

Question

当我尝试在 jboss 5 中部署产品时。 我正在为 JPA 1.0 使用 toplink-essentials。

本产品在tomcat 6上运行成功。

但在 jboss 中却显示错误。

我正在尝试通过 Eclipse IDE 部署产品。

错误输出：

这是我的 persistence.xml 文件...

<persistence 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

    <non-jta-data-source>java:/iport</non-jta-data-source>

    <class>env.model.masters.IptNotifications</class>
    <class>env.model.masters.IptNotificationslines</class>

    <properties>
        <property name="toplink.jdbc.driver"

        <property name="toplink.jdbc.user" value="xx" />
        <property name="toplink.jdbc.password" value="xx" />
    </properties>

</persistence-unit>

我正在使用 Struts 2.1.x、spring 1.2.x、jpa 1.0、toplink-essentials 2.0

请帮我解决问题...

于 2013 年 4 月 29 日编辑：

你好，任何人都可以帮助我......

我可以理解一件事，persistence.xml 和数据有问题。

在google了这么多之后，我找到了一些解决方案....比如....

1) 去掉“private static final long serialVersionUID = 1L;”来自所有pojo。

2）标签内的persistence.xml中不应有空格。

3) 从 NON-JTA 数据源更改 JTA 数据源。

我已经按照上面提到的几点改变了所有的东西。

但我仍然遇到同样的错误。

我更新的 peresistence.xml 是..

<persistence 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" version="1.0">

    <persistence-unit name="Entity" transaction-type="JTA">

    <provider>oracle.toplink.essentials.PersistenceProvider</provider>

    <jta-data-source>java:/iport</jta-data-source>

    <class>env.model.masters.IptNotifications</class>
            <class>env.model.masters.IptNotificationslines</class>

            <properties>
                <property name="toplink.jdbc.driver"
                     value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
                <property name="toplink.jdbc.url"
                     value="jdbc:sqlserver://x.x.x.x:1433;databaseName=MyDatabase" />
                <property name="toplink.jdbc.user" value="xx" />
                <property name="toplink.jdbc.password" value="xx" />
            </properties>
    </persistence-unit>

</persistence>

请验证问题。并建议我一个可能的解决方案。

我也有 orm.xml 文件。

代码如下..

<?xml version="1.0" encoding="UTF-8"?>
<entity-mappings
xmlns="http://java.sun.com/xml/ns/persistence/orm"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm orm_2_0.xsd"
version="1.0">
<persistence-unit-metadata>

    <persistence-unit-defaults>

        <schema>MySchema</schema>

        <catalog>MyDatabase</catalog>

    </persistence-unit-defaults>

</persistence-unit-metadata>
</entity-mappings>

请验证

Answer 1

TopLink Essentials 尝试加载默认的 orm.xml 文件时发生错误。你是否有一个？检查您的文件是否有效并且其命名空间等是否正确。如果您没有，您可以尝试添加一个。

也尝试升级到最新的 TopLink Essentials 补丁版本，或升级到 EclipseLink，它自 2008 年以来取代了 TopLink Essentials。

Answer 2

异常不解释太多，但至少在 Glassfish 中，transaction-type 必须设置为 JTA 而不是 persistence.xml 文件中的 RESOURCE_LOCAL，因为作为一个成熟的 Java EE Application Server，它希望有 JTA准备好用于 EJB 和注入容器管理的 EntityManager 的事务。

如果这也是 JBoss 的问题并且您正在使用 Spring，则有一些解决方法，例如将 persistence.xml 文件的名称更改为其他名称，因此 JBoss 不会尝试加载 Spring 已经处理的持久性单元.
