    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1599?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=34901#action_34901 ] 

Bruno Medeiros commented on HHH-1599:
-------------------------------------

Sorry for the double post..

I've attached a file that I tried to apply the patches above. I don't remember why I didn't extend the default dialect, but I think it's not possible to apply the patches extending.
It's far from perfect, but at least shows the constraint.

It's doesn't seem that there's someone with free enough time to spent on this...

> ConstraintViolationException.getConstraintName() returns null. The problem is that the message being parsed comes from the SqlException that is the inputparameter to extractConstraintName(SqlException) in ViolatedConstraintNameExtracter. 
> Solution. The message provided by sqlException.getMessage() is "batch bla bla something" but the correct Exception message to parse is sqlException.getNextException().getMessage()
