      Hello,

       

      I am attempting to implement a test which uses an Entity that has a @ElementCollection mapping defined. The corresponding code is similar to the following:

       

       

      @Entity
      public class SomeEntity implements Serializable {
       
          private static final long serialVersionUID = 1L;
          @ElementCollection
          private Collection<SomeEmbeddableClass> someEmbeddableClasses = new ArrayList<>();
           ...................................................................................
      }
       
       
      @Embeddable
      public class SomeEmbeddableClass implements Serializable {
       
          private static final long serialVersionUID = 1L;
          ...................................................................................
      }

       

       

      I am using a remote glassfish deployment and my pom.xml with all the versions information is the following:

      Now, when I run my test I get the following exception:

       

      Internal Exception: Exception [EclipseLink-7155] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.ValidationException
      Exception Description: The type [class jpa2.objectrelationalmapping.SomeEmbeddableClass] for the attribute [someEmbeddableClasses] on the entity class [class jpa2.objectrelationalmapping.SomeEntity] is not a valid type for a serialized mapping. The attribute type must implement the Serializable interface.. Please see server.log for more details. [status: CLIENT_ERROR reason: Bad Request]
      com.sun.jersey.api.container.ContainerException: exit_code: FAILURE, message: Error occurred during deployment: Exception while preparing the app : Exception [EclipseLink-28018] (Eclipse Persistence Services - 2.3.2.v20111125-r10461): org.eclipse.persistence.exceptions.EntityManagerSetupException
      Exception Description: Predeployment of PersistenceUnit [test] failed.

       

       

      All other Entity mappings work just fine.

      The @Embeddable class is clearly implementing the Serializable interface. Am I missing something in my configuration?

       

       

      Thanks very much,

      Savvas
