Hi,

We are using JPA annotations in a standard seam application.

I have seen this jira http://opensource.atlassian.com/projects/hibernate/browse/ANN-140 and was wondering whether this is still how things stand.

Is is not possible to use a DiscriminatorColumn when using the join inheritance strategy?

I understand that it is not required but in our case we have hundreds of classes extending a particular class. This causes the polymorphic query to be huge with too may joins slowing things down drastically.

We are using Postgres at present but plan on supporting multiple dbs. I think mysql has a limit to the number of joins in which case our model will break.

Thanks
Pieter
