Hi everyone,
Thank you Ian for your reply.
I've tried your solution but does not work for me :/
I've removed the prefix from the type name like shown in the code below
(the type name in my case is prefixed using underscore
) :
String typeNames[] = data.getTypeNames();
String typeName = typeNames[0];
FeatureSource<SimpleFeatureType, SimpleFeature> source =
data.getFeatureSource( typeName ); // here I keep the type name as returned
by the datastore
// because if I put the substring instruction before that I get an
error saying the type name does not exist !
typeName=typeName.substring(typeName.indexOf("_")+1);
Query query = new DefaultQuery( typeName );
query.setCoordinateSystem(DefaultGeographicCRS.WGS84);
FeatureCollection<SimpleFeatureType, SimpleFeature> features =
source.getFeatures( query );
FeatureIterator<SimpleFeature> fi=features.features();
try {
while( fi.hasNext() )
{
Feature feature = (Feature) fi.next();
// ....
}
}catch (Exception e)
{
e.printStackTrace();
}
I've tried another way to do that specifying explicitly the type name
parameters in the query. I did it like that :
FeatureSource<SimpleFeatureType, SimpleFeature> source =
data.getFeatureSource( typeName );
Query query = new DefaultQuery( typeName );
query.setAlias("ms");
query.setNamespace(new URI("http://mapserver.gis.umn.edu/mapserver";));
query.setCoordinateSystem(DefaultGeographicCRS.WGS84);
FeatureCollection<SimpleFeatureType, SimpleFeature> features =
source.getFeatures( query );
FeatureIterator<SimpleFeature> fi=features.features();
Unfortunately I am still not able to get my features!!
Any further help would be appreciated :)
Thank you,
Hanane
