title: Error running JPA EclipseLink application on IBM Websphere Libery Server
body: <p>I have been trying to run a <code>JPA</code> application which uses <code>EclipseLink 2.5.1</code> as a <code>JPA</code> provider on IBM Websphere Liberty Server.                   </p>
  
  <p>I am facing following exception:</p>
  
  <pre><code>[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
  </code></pre>
  
  <p>Since my application contains its own JPA EclipseLink JARS jars, I have only enabled <code>&lt;feature&gt;jpaContainer-2.1&lt;/feature&gt;</code></p>
  
  <p>Here is my POM.xml:</p>
  
  <pre><code>&lt;dependency&gt;
    &lt;groupId&gt;org.eclipse.persistence&lt;/groupId&gt;
    &lt;artifactId&gt;eclipselink&lt;/artifactId&gt;
  &lt;/dependency&gt;
  &lt;dependency&gt;
    &lt;groupId&gt;org.eclipse.persistence&lt;/groupId&gt;
    &lt;artifactId&gt;org.eclipse.persistence.jpa.modelgen.processor&lt;/artifactId&gt;      
  &lt;/dependency&gt;
  </code></pre>
  
  <p>Please help me if anyone ever faced this scenario.</p>
