将我的 JPA 应用程序部署到 Websphere 7 时出现异常

发布于 2024-11-14 19:47:00 字数 11018 浏览 2 评论 0原文

我在将 Web 应用程序部署到最新版本的 IBM Websphere 7 时遇到问题。 异常是在JPA初始化期间引起的。 该应用程序使用 servlet 2.5、eclipselink 2.1.3、java 6 update 25。 persistence.xml 使用版本 1.0

我不确定，如果此异常是由 Websphere 中的错误/配置错误或我的应用程序引起的。可能也和eclipselink有关。

更新

我们的应用程序不使用 JNDI 向 EclipseLink 提供数据源。我们的应用程序将 DataSource 直接传递到 EclipseLink（使用 EclipseLink 特定的 EntityManager 属性）

我正在使用的 persistence.xml 是（省略所有实体定义和调整属性）：

<?xml version="1.0" encoding="UTF-8"?>
<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="default" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <non-jta-data-source></non-jta-data-source>
    <class>my.applications.entity.classes.A</class>
    <!-- other class definitions follow -->
    <properties>
      <property name="eclipselink.logging.level" value="FINEST" />

      <!-- some other properties, not related to datasources/connections/JNDI 
        follow -->
    </properties>
  </persistence-unit>
</persistence>

这里是 System.err输出：

com.ibm.ws.exception.RuntimeWarning: com.ibm.ws.metadata.MetaDataException: CWWJP0018E: Incorrect syntax or error detected in /path/to/my/project/my_application_war.ear/my_application.war/WEB-INF/classes/ for application my_application_war module my_application.war.

I have problems deploying a web application to the most recent version of IBM Websphere 7.
The exception is caused during the JPA initialization.
The application is using servlet 2.5, eclipselink 2.1.3, java 6 update 25.
persistence.xml is using version 1.0

I am unsure, if this exception is caused by a bug/configuration error in Websphere or by my application. Maybe it's also related to eclipselink.

UPDATE

Our application does not use JNDI for providing datasources to EclipseLink. Our application passes the DataSource directly to EclipseLink (using EclipseLink specific EntityManager properties)

The persistence.xml I am using is (leaving out all entity definitions and tuning properties):

<?xml version="1.0" encoding="UTF-8"?>
<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="default" transaction-type="RESOURCE_LOCAL">
    <provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
    <non-jta-data-source></non-jta-data-source>
    <class>my.applications.entity.classes.A</class>
    <!-- other class definitions follow -->
    <properties>
      <property name="eclipselink.logging.level" value="FINEST" />

      <!-- some other properties, not related to datasources/connections/JNDI 
        follow -->
    </properties>
  </persistence-unit>
</persistence>

Here comes the System.err output:

空的非 jta-data-source 导致 WebSphere Application Server 执行查找（""），该查找返回根上下文，然后尝试将其转换为 DataSource。

容器管理的JPA旨在让容器获取数据源并将其传递给EM本身。我建议您在 persistence.xml 中指定数据源，或者完全禁用容器管理的 JPA 以避免应用程序启动期间出现错误：

http://www-01.ibm.com/support/docview.wss?uid=swg1PM26361

The empty non-jta-data-source is causing WebSphere Application Server to perform a lookup(""), which returns the root context, which it then attempts to cast to DataSource.

Container-managed JPA is designed for the container to acquire the data source and pass it to the EM itself. I would recommend that you either specify your data source in persistence.xml, or just disable container-managed JPA altogether to avoid the error during application start:

Websphere 似乎正在验证 persistence.xml 中的数据源值，并且它似乎无效。您需要指定一个有效值，即使您稍后要覆盖它。

请包含您的 persistence.xml。您还可以尝试不设置数据源，或者如果不允许没有数据源，则使用resource_local。

Websphere seems to be validating your data-source value in your persistence.xml, and it seems to be invalid. You need to specify a valid value, even if you are overriding it later.

Please include your persistence.xml. You could also try not setting a data-source, or using resource_local if it does not allow no data-source.
