Hello all,
Since a few weeks, i don't know why but the WFS Datastore does not work
anymore in my codes.
I'm using GeoTools 8.2.
Here the sample code I run:
/SimpleFeatureCollection result = null;//
// try{//
////
// String wfsGetCap =
"http://localhost:8080/geoserver/ows?service=WFS&version=1.0.0&request=GetCapabilities";//
////
// // use the WFS Datastore//
// Map<String, Serializable> params = new HashMap<String,
Serializable>();//
// params.put(WFSDataStoreFactory.URL.key, wfsGetCap);//
// params.put(WFSDataStoreFactory.TIMEOUT.key, new
Integer(60000));//
////
// DataStore datastore = DataStoreFinder.getDataStore(params);//
// SimpleFeatureSource featureSource =
datastore.getFeatureSource("mylayer");//
////
////
// result = featureSource.getFeatures();//
////
// }catch(Exception e){//
// new RuntimeException("Unable to get the target
collection", e);//
// }//
////
//System.out.println(result.size());/
and the error i get:
/Exception in thread "main" java.lang.NoSuchMethodError:

Could somebody help me in identifying what's the issue and solve it?
In other case, does anyone know an efficient way to get feature
collections from WFS (possibly applying a filter)?
Thanks in advance
Emmanuel
