[RynekMedyczny (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4413?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=39306#action_39306 ] 

RynekMedyczny commented on HHH-4413:
------------------------------------

Is there any progress on this issue?
Are there any known workarounds?

Not being able to use interfaces with Hibernate Annotations is really inconvenient for Hibernate users :(

Kind Regards

> It should be possible to create a mapping with interfaces, as described by the documentation here: http://www.hibernate.org/hib_docs/v3/reference/en/html_single/#inheritance-tableperclass
> Specifically right now it is impossible to annotate interfaces and according to HBX-231 even if you could @Entity is only meant to get used on classes so the question becomes "what do you annotate it with?"
> As I pointed out here http://forum.hibernate.org/viewtopic.php?p=2238824#2238824 the additional problem seems to be that XDoclet doesn't support interface annotation either (http://opensource.atlassian.com/projects/xdoclet/browse/XDT-1345) so I'm left without a workaround.
> I can't convert the interfaces to abstract classes because I implement multiple interfaces in my application and Java does not do multiple inheritance.
> If you know of a nice workaround, please let me know :)
