Hi people,
I have a problem with my FeatureWriter. I try to write some features from a
shape file to a geoserver (v. 1.0.0), using geotools 2.4 .
Here a part of my code:
WFSDataStoreFactory wfsStoreFactory = new WFSDataStoreFactory();
DataStore ds = wfsStoreFactory.createDataStore(params);
Transaction tx = new DefaultTransaction();
FeatureWriter featureWriter =
ds.getFeatureWriterAppend("topp:USK_GF_ERGEBNIS", tx);
// Some other code
while( iterator.hasNext() ){
Feature feature = iterator.next();
Feature wfsFeature = featureWriter.next();
wfsFeature = feature;
featureWriter.write();
}
Following Exception is thrown:
Exception in thread "Thread-0" java.lang.NullPointerException

Somebody an idea how to solve that problem? Or another way to save features on
a geoserver?
