title: Spring-MVC-4 + JPA 2 + Hibernate Validation 5.0.2 on Weblogic 10.3.6
body: <p>after many search on the web I have not yet found a solution.
  I use JPA 2 on WebLogic 10.3.6.
  Everything works well on tomcat:</p>
  
  <pre><code>@RequestMapping(value="/createUser", method = RequestMethod.POST)
  public String create(@Valid Utente utente, BindingResult result)
  </code></pre>
  
  <p><br>
  but when I deploy to WebLogic I get this Exception:</p>
  
  <pre><code>java.lang.AbstractMethodError: org.apache.openjpa.persistence.PersistenceProviderImpl.getProviderUtil()Ljavax/persistence/spi/ProviderUtil;
  at javax.persistence.Persistence$PersistenceUtilImpl.isLoaded(Unknown Source) ~[javax.persistence_1.1.0.0_2-0.jar:2.0.3]
  at org.hibernate.validator.internal.engine.resolver.JPATraversableResolver.isReachable(JPATraversableResolver.java:56) ~[hibernate-validator-5.0.2.Final.jar:5.0.2.Final]
  </code></pre>
  
  <p><br>
  This is pom.xml:</p>
  
  <pre><code>&lt;dependency&gt;
      &lt;groupId&gt;org.springframework&lt;/groupId&gt;
      &lt;artifactId&gt;spring-webmvc&lt;/artifactId&gt;
      &lt;version&gt;4.0.0.RELEASE&lt;/version&gt;
  &lt;/dependency&gt;
  ...
  &lt;dependency&gt;
      &lt;groupId&gt;org.hibernate&lt;/groupId&gt;
      &lt;artifactId&gt;hibernate-validator&lt;/artifactId&gt;
      &lt;version&gt;5.0.2.Final&lt;/version&gt;
  &lt;/dependency&gt;
  </code></pre>
  
  <p>Thanks in advance</p>
