[Geotools-gt2-users] GML : null:TYPE

[sunish <sun...@gm...>]

Hello,

Recently I migrated to Geotools 24 from version 12.3

I am facing an issue in GML encoder with the following code.


        SimpleFeatureType featureType = DataUtilities.createType("TYPE",
"the_geom:Polygon,name:\"\",tag:\"\"");
        SimpleFeatureBuilder featureBuilder = new
SimpleFeatureBuilder(featureType);
        WKTReader reader = new WKTReader(geometryFactory);
        ListFeatureCollection collection = new
ListFeatureCollection(featureType);
       ...........
       ............
        ByteArrayOutputStream xml = new ByteArrayOutputStream();

        GML encode2 = new GML(GML.Version.WFS1_0);
        encode2.setBaseURL(new URL("http://localhost/gml"));
        encode2.setNamespace("location", "plot.xsd");
        encode2.encode(xml, collection);

The generated GML has a tag like this.

*<null:TYPE gml:id="fid-236fab5a_1753cf2b2e0_5f2f">*

Please help me to solve this.

Thank you.
