[Geotools-gt2-users] Writing to a postgis database with 4 dimensional coordinates

[Diego J. <die...@gm...>]

Hi!

I'm trying to write a geometry to a postgis database which has a 
constraint that only allows 4D coordinates:

CONSTRAINT enforce_dims_the_geom CHECK (st_ndims(the_geom) = 4

I'm using a a GeometryFactory to create my geometries and I have tried 
to set a hint:

GeometryFactory factory = JTSFactoryFinder.getGeometryFactory(new 
Hints(Hints.COORDINATE_DIMENSION, new Integer(4)));
Geometry geom = factory.createPoint(new Coordinate(100, 101, 102));

However, this does not work and postgres complains with a:

new row for relation "Geometry" violates check constraint 
"enforce_dims_the_geom".

I need to write the data with a Postgresql Connection and so I did:

WKBWriter writer = new WKBWriter();
PreparedStatement st = con.prepareStatement("INSERT INTO 
\""+TABLE_NAME+"\" " +
                                             "("+THE_GEOM+") " +
                                             "VALUES (?)", 
PreparedStatement.RETURN_GENERATED_KEYS);
st.setBytes(1, writer.write(g.mGeometry));

How can I write the geometry with 4D coordinates?

Thanks
