[Geotools-gt2-users] Problem in showing Layer on JmapPane

[kapil <kap...@gm...>]

Hi List,

I want to show a map on JmapPane, but i found exception when i run the code.
Here is my code:

ResultSet res = stmt.executeQuery(sql);
            SimpleFeatureCollection col =
org.geotools.feature.FeatureCollections.newCollection();
            while (res.next()) {
               
                col.add(PolygonFeatureHelper.createPolyFeature(new
WKTReader().read(res.getString("the_geom")), res.getString("kide")));
            }
            
            StyleBuilder sb = new StyleBuilder();
            MapStyleSetings mapSty = new MapStyleSetings();
            //..............................
             Irrelevent code
            //
            MapContent context = new MapContent();

            villageLayer = new FeatureLayer(col, archStyle, "Khasra");
            System.out.println("VILLAGELAYER"+villageLayer);
       

            context.addLayer(villageLayer);
    
           
            mapPane.setMapContent(context);
