Hi community,
I'm trying to encode some KML and I'm getting an error. I don't understand
why. This is the error:
Exception in thread "main" java.lang.NullPointerException
at
org.geotools.xml.impl.SchemaIndexImpl.destroy(SchemaIndexImpl.java:100)
at org.geotools.xml.Encoder.encode(Encoder.java:1026)
at org.geotools.xml.Encoder.encode(Encoder.java:566)
at xsdtest.main(xsdtest.java:44)
An this is my code:
import java.io.ByteArrayOutputStream;
import java.util.HashMap;
import java.util.Map;
import org.geotools.data.DataStoreFinder;
import org.geotools.data.DataStore;
import org.geotools.data.simple.SimpleFeatureIterator;
import org.geotools.data.simple.SimpleFeatureSource;
import org.geotools.data.simple.SimpleFeatureCollection;
import org.geotools.kml.KML;
import org.geotools.kml.KMLConfiguration;
import org.geotools.xml.Encoder;
import org.opengis.feature.simple.SimpleFeature;
public class xsdtest {
public static void main(String[] args) throws Exception {
DataStore dataStore;
String server = "
http://www.sogis1.so.ch:8080/geoserver/ows?service=WFS&request=GetCapabilities
";
String layer = "topp:states"; // Feature TypeName
Map<String, Object> connectionParameters = new HashMap<String,
Object>();
connectionParameters.put("WFSDataStoreFactory:GET_CAPABILITIES_URL",
server);
dataStore = DataStoreFinder.getDataStore(connectionParameters);
SimpleFeatureSource featureSource =
dataStore.getFeatureSource(layer);
SimpleFeatureCollection featureCollection =
featureSource.getFeatures();
SimpleFeatureIterator featuresIterator =
featureCollection.features();
Encoder encoder = new Encoder(new KMLConfiguration());
ByteArrayOutputStream out = new ByteArrayOutputStream();
while (featuresIterator.hasNext()) {
SimpleFeature feature = featuresIterator.next();
encoder.encode(feature, KML.Placemark, out);
String kmlString = new String(out.toByteArray());
System.out.println(kmlString);
}
}
}
What I'm doing wrong? Any ideas?
Thank you very much.
Edu.
