*My Problem:*
When I try insert a Geometry by WFS 1.0.0, Geotools thows this Exception:
*java.lang.NullPointerException*

**public static void addFeatures(String layer, Listst<Map<String, Object>>

* *
* wfsDataStore = (new

* *
* featStore = (FeatureStore<SimpleFeatureType, SimpleFeature>)
featSource; *
* featStore.setTransaction(insert);*

* }*
* //null para que genere un id por defecto*
* feat = featBuilder.buildFeature(null);*
* collection.add(feat);*
* }*
* *
* featStore.addFeatures( collection );*
* insert.commit(); *
* } *
* catch (MalformedURLException e) {*
* e.printStackTrace();*
* } *
* catch (IOException e) {*
* e.printStackTrace();*
* }*
* }*
Excuse my English, any idea I would be very useful.
*Thank you very much*
