One approach could be to query the Dynamic layers for the extents and then use that to implement the Zoom to Layer.          HttpClient client = new DefaultHttpClient();          HttpPost post = new HttpPost(MapServiceUrl + "/dynamicLayer?");          List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);          nameValuePairs.add(new BasicNameValuePair("layer", queryParam));          post.setEntity(new UrlEncodedFormEntity(nameValuePairs));          HttpResponse response = client.execute(post);          BufferedReader rd = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); Where queryParam can be formed from dynamics layers String queryParam= "{\"id\":0,\"source\":{\"type\":\"dataLayer\",\"dataSource\":{\"type\":\"" + type + "\",\"workspaceId\":\"" + workspaceId + "\",\"dataSourceName\":\"" + layerName + "\"}}}"; You can put type = "table" for Feature Layers, Workspaceid can be obtained from the added dynamic layer and layername in the name of the shapefile or layer that was added. You can then parse this using the Json parser and get the required extents or any other info that is required JsonNode extentNode = parseJson(rd).findValue("extent"); extentNode.findValue("xmin").asDouble(); extentNode.findValue("ymin").asDouble(); extentNode.findValue("xmax").asDouble(); extentNode.findValue("ymax").asDouble(); Here is the method for parsing JSON private static JsonNode parseJson(BufferedReader jsonStr) {    JsonFactory jfactory = new JsonFactory();    JsonNode rootNode = null;    try {     ObjectMapper mapper = new ObjectMapper(jfactory);     rootNode = mapper.readTree(jsonStr);    } catch (JsonParseException e2) {     e2.printStackTrace();    } catch (Exception e2) {     e2.printStackTrace();    }    return rootNode;     } I hope this helps !!!! The ArcGIS Runtime sample "Datasources > Add Shapefile" provide source code to select a shapefile and add it to the map based on a blank MPK (Map Package) and a map service (on the LocalServer). From that, I would like to be able to get the Full Extent of this layer (from menu "Zoom To Layer"). In my case, I have a World wide blank MPK, so any kind of Shapefile will be loaded. basically, from 2 identical blank MPK, I can load 2 different Shapefile, one with European countries, another with USA countries. I need to be able to zoom to first Layer on "Europe" or to second layer on "USA" ! But my issue is : - if I try to get the full extent from the Dynamic Layer, with getFullExtent(), I will get the Envelope from the MPK which is always the World extent. - How can I get the Full Extent from sub-layers of the dynamic layer to only get the Envelope of my Shapefile (sublayer[0]) ?? ...

Thanks....There were some issues with the case-sensitivity in the request. Now the Query works fine. I tried the REST API way for the Labeling. I dont get any errors and get an image back but its not labeled. On checking the rest api documentation I find that "If dynamicLayer resource lists canModifyLayer to be false, then only the label properties specified in drawingInfo are honored - use showLabels to turn on/off labels and use labelingInfo to specify how the labels are drawn." http://resources.arcgis.com/en/help/rest/apiref/index.html?ms_dyn_query.html That puts a limitation on dynamic layers? Hi, You won't be able to do Identify or Labeling using the 'dynamic workspaces' functionality (i.e. ad hoc adding of data rather than through a map package / mpk) at 10.1.1, but the REST API does support query on dynamic layers. The Java SE Runtime API doesn't have support within the Query classes for this, but look for this at 10.2. For now to query a dynamic-workspace-style layer, e.g. a shapefile, you would need to construct your own query request, an example is on this page: http://resources.arcgis.com/en/help/rest/apiref/ms_dyn_query.html e.g. Example 1, where 'layer={...}' could be obtained in code from the DynamicLayerInfo of the layer you want to query. If you'd like more information let me know, ~elise ... View more
