We still use GeoTools but we don't work with GeoServer. When we  
needed to write features to the database we found that it was easier  
to use Hibernate Spatial directly. In our architecture we now have a  
LayerModel that retrieves and persists data. The LayerModel can  
retrieve objects either through a GeoTools datasource, or through  
Hibernate. The first we use for read-only data, and the second for  
read-write data and/or complex relational object models. Of course,  
if you use GeoServer you don't have the choice and have to implement  
a DataStore.

We also felt that it is an advantage to be able to work with POJO's  
without needing special classes or interfaces such as Feature simply  
because some business object is Geometry-valued.
