Question

我一直在尝试运行JPA应用程序，该应用程序在IBM Websphere Liberty Server上使用EclipseLink 2.5.1作为JPA提供程序。

我面临以下异常：

[ERROR   ] CWWJP0015E: An error occurred in the org.eclipse.persistence.jpa.PersistenceProvider persistence provider when it attempted to create the container entity manager factory for the XXXXX persistence unit. The following error occurred: Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Predeployment of PersistenceUnit [XXXXXX] failed.
Internal Exception: Exception [EclipseLink-28006] (Eclipse Persistence Services - 2.5.1.v20130918-f2b9fc5): org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: ClassNotFound: [WebSphere_Liberty] specified in [eclipselink.target-server] property.
Internal Exception: java.lang.ClassNotFoundException: WebSphere_Liberty

由于我的应用程序包含自己的JPA EclipseLink JARS jar，我只启用了<feature>jpaContainer-2.1</feature>

这是我的POM.xml：

<dependency>
  <groupId>org.eclipse.persistence</groupId>
  <artifactId>eclipselink</artifactId>
</dependency>
<dependency>
  <groupId>org.eclipse.persistence</groupId>
  <artifactId>org.eclipse.persistence.jpa.modelgen.processor</artifactId>      
</dependency>

如果有人遇到过这种情况，请帮助我。

我只是在自己设置过程中，看来，你必须定义一个铃声（对我来说，我尝试休眠，可能只是用eclipselink取代）：

在server.xml中

<feature>jpaContainer-2.1</feature>
<feature>bells-1.0</feature>
.
.
.
<bell libraryRef="hibernate" />
<!-- Include all of the hibernate jars in a shared lib -->
<library id="hibernate">
   <fileset dir="${server.config.dir}/hibernate/" includes="*.jar" />
</library>

所以，你实际上必须将这些罐子组装到正确的文件夹中，然后将你的钟指向libs目录。
