Support for 3d point?

[eroussel]

Hello,

I would like to know if the current release of Hibernate Spatial  
supports 3d points on PostGIS, and if yes, if there is any example of  
how to do that.

Thanks in advance.

Yes, 3D points are supported. You just need to create an object with  
a point geometry attribute (JTS Geometry package), set its X,Y,Z  
coordinates, then persist it using Hibernate. Check also the tutorial  
on http://www.hibernatespatial.org/tutorial.html

Thanks. I got it working; what prompted my question was that while querying the DB (with SQL) after inserting 3D waypoints I was unable to output the Z value. But by programmatically querying the DB from Java and logging the returned entities I was able to prove that the Z value was actually stored in the DB. I don't know exactly why I couldn't retrieve the Z value from PostgreSQL/PostGIS directly however.
