Hibernate seems to be keeping the details behind my problem a secret, not sure how to uncover some helpful debugging info.
Anyone know how to get more info than this out of hibernate (IMHO it should provide this by default) ?
I am really looking more for suggestions on how to get hibernate to display more useful information to be able to better understand the issue.
