Good morning Bart: I have not had an opportunity to assist, some of the code you are trying represents my attempt to get this working when it was initially written. I find that the best approach is to look at a geotools test-case which does what you want - and then step through with a debugger to see how the objects were setup and to review the structure of the objects (in this case a GMLConfiguration).
I searched using: https://github.com/geotools/geotools/search?l=Java&q=3.2+gml+simplefeature+test And found: https://github.com/geotools/geotools/blob/main/modules/extension/xsd/xsd-gml3/src/test/java/org/geotools/gml3/GML3EncodingTest.java -- Jody Garnett On Mon, Apr 3, 2023 at 4:11 AM Bart Adriaanse <bart.adriaa...@gmail.com> wrote: > Hi there, > > I have been struggling with this for some time, even after investigating > the source code of both Geotools and GeoServer i cannot seem to get this to > work. > > I have a extremely simple WFS 1.0 interface in an application and need to > update this to WFS 2.0 but i am stuck at encoding a SimpleFeatureCollection > to GML 3.2 > > I would be very grateful if someone who is very familiar with Geotools can > find some time to see what is wrong with my code, here is a copy of the > Junit test i am trying to get to work: > > import org.geotools.data.DataUtilities; > import org.geotools.data.collection.ListFeatureCollection; > import org.geotools.data.simple.SimpleFeatureCollection; > import org.geotools.feature.simple.SimpleFeatureBuilder; > import org.geotools.feature.simple.SimpleFeatureTypeBuilder; > import org.geotools.gml3.v3_2.GML; > import org.geotools.gml3.v3_2.GMLConfiguration; > import org.geotools.wfs.WFS; > import org.geotools.xsd.Encoder; > import org.junit.Assert; > import org.junit.Test; > import org.locationtech.jts.geom.Coordinate; > import org.locationtech.jts.geom.GeometryFactory; > import org.locationtech.jts.geom.Point; > import org.opengis.feature.simple.SimpleFeature; > import org.opengis.feature.simple.SimpleFeatureType; > > import javax.xml.namespace.QName; > import java.io.ByteArrayOutputStream; > import java.io.IOException; > import java.nio.charset.StandardCharsets; > > public class EncodeGML3_2Example { > > @Test > public void encodeGML32() { > try { > // Create a SimpleFeatureType > SimpleFeatureTypeBuilder typeBuilder = new SimpleFeatureTypeBuilder(); > typeBuilder.setName("SampleFeature"); > typeBuilder.add("geom", Point.class); > typeBuilder.add("name", String.class); > SimpleFeatureType featureType = typeBuilder.buildFeatureType(); > > // Create and add features to SimpleFeatureCollection > ListFeatureCollection featureList = new ListFeatureCollection(featureType > ); > SimpleFeatureBuilder featureBuilder = new SimpleFeatureBuilder(featureType > ); > GeometryFactory geometryFactory = new GeometryFactory(); > Point point1 = geometryFactory.createPoint(new Coordinate(10, 10)); > featureBuilder.add(point1); > featureBuilder.add("Point 1"); > SimpleFeature feature1 = featureBuilder.buildFeature("1"); > Point point2 = geometryFactory.createPoint(new Coordinate(20, 20)); > featureBuilder.add(point2); > featureBuilder.add("Point 2"); > SimpleFeature feature2 = featureBuilder.buildFeature("2"); > featureList.add(feature1); > featureList.add(feature2); > SimpleFeatureCollection featureCollection = DataUtilities.collection( > featureList); > > // Encode the SimpleFeatureCollection as GML 3.2 > GMLConfiguration gmlConfig = new GMLConfiguration(true); > Encoder encoder = new Encoder(gmlConfig); > encoder.setSchemaLocation("http://www.opengis.net/gml";, " > http://schemas.opengis.net/gml/3.2.1/gml.xsd";); > encoder.setNamespaceAware(true); > encoder.setRootElementType(WFS.FeatureCollection); > String gml = encoder.encodeAsString(featureCollection, GML. > FeatureCollection); > > Assert.assertTrue(!gml.isEmpty()); > > } catch (Exception e) { > e.printStackTrace(); > } > } > > } > _______________________________________________ > GeoTools-GT2-Users mailing list > GeoTools-GT2-Users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/geotools-gt2-users >
