Adding Labels to a Vector Map with Java Mapscript

[Umberto Nicoletti]

Try this modifications:

Capa = new layerObj(Mapa);
            Capa.setName("Vias");
            Capa.setType(mapscriptConstants.MS_LAYER_LINE);
            Capa.setStatus(mapscriptConstants.MS_ON );
            String Comando = new String("the_geom FROM (select gid,
the_geom, nomb_comun||' '||nomvial as Nombre FROM "+Localidad+" WHERE
codigo IN ("+CodigoVia+","+CodigoInterseccion+")) AS ViasMapa USING
UNIQUE gid USING SRID=-1");
            Capa.setData(Comando);
            Capa.setLabelitem("Nombre");
            Capa.setConnection("user=geotrans dbname=Geotrans host=localhost");
            Capa.setConnectiontype (mapscriptConstants.MS_POSTGIS);
            Clase = new classObj(Capa);
// CHANGE FROM HERE
            Clase.setName('Pick a name');
// comment out the style
//            Estilo = new styleObj(Clase);
//            Estilo.setColor(new colorObj(255,0,0,0));
// and use this to set the color instead
            Clase.setColor(new colorObj(255,0,0,0));
// END OF CHANGE
            labelObj Etiquetas = new labelObj();
            Etiquetas.setSize(18);
            Etiquetas.setColor(new colorObj(0,255,255,0));
            Etiquetas.setType(mapscriptConstants.MS_TRUETYPE);
            Etiquetas.setAntialias(mapscriptConstants.MS_TRUE );
            Etiquetas.setPosition(mapscriptConstants.MS_CL);
            // CHANGE: comment this too
            //Etiquetas.setPartials(mapscriptConstants.MS_FALSE);
            //Etiquetas.setMindistance(300);
            Etiquetas.setFont("vera");
            Clase.setLabel(Etiquetas);
            Mapa.draw().save("/usr/local/tomcat/webapps/geotrans/Mapas/mapaAcc",null);

You could also try to save the map to a file to make sure everything
got setup properly in mapscript. To do this simply call
Mapa.save('filename'); then post the map file to the list.

Umberto
