I haven't used any WFSDataStore's yet...but it should work fine. The type of
DataStore should not be an issue. It should be easy to substitute that into
the example code and give it a go...

Hi Jeff,
thanks for the Example, another little question.
Im using a WFSDataStore like that
URL url=new
URL("http://beaker.sysgroup.it/geoserver/wfs?version=1.0.0&request=getcapabilities&service=wfs";);
Map m = new HashMap();
m.put(WFSDataStoreFactory.URL.key,url);
DataStore wfs = (new WFSDataStoreFactory()).createNewDataStore(m);
Can I use the same procedure of your example?
Best regards.
Jacopo

Jacopo,
The below is a quick example of a getFeatures() operation with a FID filter

public static void main(String[] args) {
URL sourceShapeFileURL = null;
ShapefileDataStore store = null;
try {

//pull the first name off of the typeNames list in the file

} catch (IOException e) {

}
//now create a FID filter and apply it to get results
FilterFactory filterFactory =
FilterFactoryFinder.createFilterFactory();
FidFilter filter = filterFactory.createFidFilter();
filter.addFid("carmel.22"); //carmel.22 is a valid FID in this
shapefile.
FeatureResults r = null;
int featureCount = 0;
try {
r = source.getFeatures(filter);
//the getCount() method below is deprecated, but works for a
quick example
featureCount = r.getCount();
} catch (IOException e) {
e.printStackTrace();
}
System.out.println("caught " + featureCount + " features with
filter");
}
}
