Hi all
I´ve a problem while querying PostGIS layers using methods queryByPoint,
queryByRect always returns the first register on database. I´m using mapserver
4.10 over windows xp and javamapscript. PostgreSQL version is 8.2.3 and
i´m using the postgis version included on that distribution.
This is the code i use:
.
.
.
.
.
.
pointObj puntoElem = new pointObj(0,0,0);
double dX = Double.parseDouble(request.getParameter("x"));
double dY = Double.parseDouble(request.getParameter("y"));
puntoElem.setX(dX);
puntoElem.setY(dY);
mapObj mapa = (mapObj)request.getSession(true).getAttribute("mapa");
layerObj layer = mapa.getLayerByName("Nuevos Elementos");
int res = layer.queryByPoint(mapa, puntoElem, mapscriptConstants.MS_SINGLE,
-1);
.
.
.
.
.
.
.
Can somebody help me?
thank in advance
