Hi Thanks for your reply, The point is I have created a map based web application using and retrieving Spatial data (Points, Polylines and Polygons) from a PostGis database. I developed it using PHP/JS and it quickly got unmanageable. So I decided to switch to JEE (at least the servlet container side + JPA) and GWT. I used to retrieve all the spatial data (Geometries) using direct SQL queries and send the data to teh client with JSON. Now I am using EclipseLink as a JPA provider but there is no support for the geometry type, as well I am using RPC for the client server talks and there is no out of the box classes for Geometry support that can be serialised on both ends. I read some people have used Hibernate Spatial for the Spatially enabled ORM. I have never found anything about an ORM + GWT end to end solution for my problem. I was just wondering if anybody had faced this problem before and how they had solved it.
