[udig-users] Open GML local file

[Alberto Debiasi <debiasi.alberto@xxxxxxxxx>]

Hi everybody.

I tried to open a GML local  file (I tried with different GML local  files ) using GeoTools (the same used in Udig) with this code:


public static void main(String[] args) {
    try{
    //create the parser with the gml 3.0 configuration
    org.geotools.xml.Configuration configuration = new org.geotools.gml3.GMLConfiguration();
    org.geotools.xml.Parser parser = new org.geotools.xml.Parser( configuration );

    //the xml instance document above
   InputStream xml = new FileInputStream("result2.gml");

     SimpleFeatureCollection fc = (SimpleFeatureCollection) parser.parse( xml );
      MapContext map = new DefaultMapContext();
      map.setTitle("Quickstart");
      map.addLayer(fc, null);

      // Now display the map
      JMapFrame.showMap(map);
    }catch(Exception e){
        e.printStackTrace();
    }
}}

but it returns these exceptions:

Why there are problems?
