Re: Use of GWT (+ JTS) + JPA + Postgis

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.

Cheers and happy new year to all,

Thomas
