    JPA Hibernate Custom Collections - Possible?

    Florian Petersen Newbie

      Hi folks,


      i have read some blogs about using custom collection classes in JPA/Hibernate mappings, but all past tries were unsuccessful. I have implemented UserCollectionType (also heard of CustomCollectionType)...


      Now e.g. in this article
      http://www.javalobby.org/java/forums/m91832311.html
      as well as in the test examples coming with Hibernate 3.1 an attribute called 'collection-type' is used in mapping file.
      Unfortunately i did not find a corresponding annotation, and i am using JPA/Hibernate annotations throughout the whole application.


      So my questions are:
      -How can i define a custom collection by using annotations instead of a mapping file?
      -Alternatively: Is there a way to use annotations and mapping file together, even for the same entity? I guess not?!?
      -Has anyone a working example?


      I am using Seam 2.2.0GA, by the way...
      Thanks a lot, best regards
      Flo
