Hi Justin, Andrea,
here's my code. The WFS (GeoServer) request included should work as an
example.
public static void main(String[] args) {
try {
InputStream in = new
URL("http://pisa007.pisa.intecs.it/geoserver/wfs?request=GetFeature&service=WFS&version=1.0.0&typeName=topp:Portugal_Creation_20Points";)
.openStream();
Configuration configuration = new WFSConfiguration();
configuration.getProperties().add(
Parser.Properties.IGNORE_SCHEMA_LOCATION );
configuration.getProperties().add(
Parser.Properties.PARSE_UNKNOWN_ELEMENTS );
Parser parser = new Parser(configuration);
Map map = (Map) parser.parse(in);
List members = (List) map.get( "featureMember" );
for ( Iterator i = members.iterator(); i.hasNext(); ) {
Map f = (Map) i.next();
Point point = (Point) f.get( "pointProperty" );
}
in.close();
} catch (Throwable t) {
t.printStackTrace();
}
I also tried with a streaming parser:
(...)
String xpath = "//Point";
StreamingParser parser = new StreamingParser( configuration, in,
xpath );
Point f = null;
while( (f = (Point) parser.parse()) != null ) {
// do something
}
(...)
but with the same effect:
Exception in thread "Thread-0" java.lang.RuntimeException:

Also the same for the GMLConfiguration.
Hope this helps. Thanks again for your help.
