Basis is an open-source project providing commonly-required components such as user management, login/authentication, role-based access management/authorization and Hibernate support classes.
The data models are derived from The Data Model Resource Book by Len Silverton and adapted for Hibernate.
Unlike other open-source projects, Basis was never meant to be used as-is, but rather as a starting point for your individual project needs.
Current version : 0.1-alpha
Notes: 01-alpha is complete, but not release-quality. Still, do take it for a trial run.
Basis is released under the BSD license (includes software from the Apache foundation).
Big thanks to Gesakon GmBH for sponsoring development of Basis, and generously allowing it to be open-sourced.
There is quite some code providing a web-based UI using WebWork/Velocity which is not ready for release yet.
Test cases exist, but they're pretty out-dated!
