Hello ,
I made a request WMS / GetFeatureInfo to have the features contained in the
layer as a work in uDig" info button".But there are only few layers where it
makes features like "A sample ArcGrid file" but for example "USA population" it
gives me "no features were found" while there are several by this manipulation
in uDig. What is the error in my code? Perhaps the parse coordinates from
double to int? is there a method to know the table schema that contains the
features in a layer?
Code:
GetMapRequest getMapRequest = wms.createGetMapRequest();
getMapRequest.setSRS("EPSG:4326");
getMapRequest.setDimensions("400", "400");
getMapRequest.setFormat("image/png");
getMapRequest.setBBox("-114.01268,59.4596930,-113.26043,60.0835794");
getMapRequest.addLayer(wmsLayerSelected);
GetFeatureInfoRequest request =
wms.createGetFeatureInfoRequest(getMapRequest);
// We want request this layer
request.addQueryLayer(wmsLayerSelected);
// coordinates with click OnMouse in the map
request.setQueryPoint((int)ev.getMapPosition().x,(int)ev.getMapPosition().y);
// We ask the server
GetFeatureInfoResponse response=null;
try {
response = (GetFeatureInfoResponse) wms.issueRequest(request);
} catch (ServiceException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
BufferedReader in = new BufferedReader(new
InputStreamReader(response.getInputStream()));
String line;
while ((line = in.readLine()) != null) {
System.out.println(line);
Thank you in advance :)
