Not everything in the GeoTools code base is ready for public abuse quite yet; for the longest time we kept such experiments to ourself. Recently we have switched to Maven and we have been able to "deploy" some of these jars for those of you wanting a sneak peek.
The following modules are provided for your amusement only; you can use these pages to swap tips, horror stories and we hope collaborate on making these modules part of our library:
But I really need ...
Several of the unsupported modules (for example Oracle) are really popular. That does not however mean that there is anyone in the GeoTools community taking care, fixing bugs and providing documentation. In some cases these modules are the work of students, in others a commercial company that donated the code (but in both cases more resources are needed to make the module usable and trustworthy).
In the past we simply threw out such work - we are trying a change of policy here by letting you see what can be done (and has been done).
If you really do need one of these modules cleaned up, perhaps for a deadline, please check out our support page - a range of commercial support options are available. Any one of these organizations can be hired to bring these modules up to speed.
