Hi Mark,
Unfortunately, depending on the WFS server, and the backend datasource
it is using it might report the geometry type as a specific type, or
just as a generic geometry type, which I am guessing is happening in
this specific case.
One option would be to "morph" the feature type you get back from the
WFS and explicitly set its geometry type to point. For example:
SimpleFeatureType schema = ...;
SimpleFeatureTypeBuilder tb = new SimpleFeatureTypeBuilder();
tb.setName( schema.getName())
tb.setCRS( schema.getCoordinateReferenceSystem());
for ( AttributeDescriptor at : schema.getAttributeDescriptors() ) {
String name = at.getLocalName();
Class type = at.getType().getBinding();
if ( at instanceof GEometryDescriptor ) {
type = Point.class;
}
tb.add(name,type);
}
schema = tb.buildFeatureType();
And then create the shapefile with that schema.
A second option if you are using geoserver is to use the SHAPE-ZIP
output format, which gives you back a zipped shapefile. Not sure if you
are using geoserver though.
