This tool allows you to view a Hibernate database as objects. You can query using HQL, Browse a Class tree or search the toStrings of every object in the database. It's released under the LGPL. So you can use it for debugging in your projects.

If this thing made its way into the core tools I'd be very happy

Hibernate tools originally contained a swing based query editor but it just got too cumbersome to maintain both swing and swt versions.

Needs someone to maintain and at least someone to contribute it. Then things can happen.
