EJB3 Geometry annotations, but they are split between JBoss users, and pure
Hibernate/Spring users – it works well in either environment. Since
it is possible to mark a property of an entity as @Geometry and then have it
persist and retrieve from PostGIS then the investigation was a success, and I
am using it in more projects (and once my current deadlines are out of the way,
I want to do some more to the codebase).<o:p></o:p></span></font></p>

<br>
I would like to use the SpatialEJB3 JBoss container for my JBoss Web Service.<br>
<br>
The SpatialEJB3 [ <a

] seems to be exactly what I want, but I do have some concerns before I invest
some time in this.....<o:p></o:p></span></font></p>

Investigation: "<i><span style='font-style:italic'>Spatial EJB3 is a
