Load and display local shapefile on a disconnected system

Question

Hi,

I am building an offline (permanently disconnected system) application. I need to load a combination of raster and shapefiles as different layers. Is there a sample program available to demonstrate this in 100.9 or above.

Is it also possible to load and display it without the base map?

thanks in advance

TileCache tileCache = new TileCache("\local_server\mpk_blank.mpk");
ArcGISTiledLayer tiledLayer = new ArcGISTiledLayer(tileCache);
Basemap basemap = new Basemap(tiledLayer);
// ArcGISMap map = new ArcGISMap(Basemap.createStreetsVector());
ArcGISMap map = new ArcGISMap(basemap);

mapView = new MapView();
mapView.setMap(map);

// create a shapefile feature table from the local file
File shapefile = new File(System.getProperty("data.dir"), "\san_diego_boundary_datasd.shp");
ShapefileFeatureTable shapefileFeatureTable = new ShapefileFeatureTable(shapefile.getAbsolutePath());
// use the shapefile feature table to create a feature layer
featureLayer = new FeatureLayer(shapefileFeatureTable);
featureLayer.addDoneLoadingListener(() -> {
if (featureLayer.getLoadStatus() == LoadStatus.LOADED) {
Alert alert = new Alert(Alert.AlertType.INFORMATION, "loaded success...");
alert.show();
} else {
Alert alert = new Alert(Alert.AlertType.ERROR, featureLayer.getLoadError().getMessage());
alert.show();
}
});

// add the feature layer to the map
map.getOperationalLayers().add(featureLayer);
//add the map view to the stack pane
stackPane.getChildren().add(mapView);

Thanks for the reply. I still don't see anything on the map in disconnected mode. Any suggestion on what could be wrong here? ////////////////////////////////////////////////////////////////////////// public class LocalServerMapImageLayerSample extends Application { private static final int APPLICATION_WIDTH = 800; private ArcGISMapImageLayer imageLayer; // keep loadable in scope to avoid garbage collection private MapView mapView; private LocalMapService mapImageService; private ProgressIndicator imageLayerProgress; @Override public void start(Stage stage) { try { // create stack pane and application scene StackPane stackPane = new StackPane(); Scene scene = new Scene(stackPane); // set title, size, and add scene to stage stage.setTitle("Local Server Map Image Layer Sample"); stage.setWidth(APPLICATION_WIDTH); stage.setHeight(700); stage.setScene(scene); stage.show(); // create a view with a map and basemap ArcGISMap map = new ArcGISMap(Basemap.createStreets()); mapView = new MapView(); mapView.setMap(map); // track progress of loading map image layer to map imageLayerProgress = new ProgressIndicator(ProgressIndicator.INDETERMINATE_PROGRESS); imageLayerProgress.setMaxWidth(30); // check that local server install path can be accessed if (LocalServer.INSTANCE.checkInstallValid()) { LocalServer server = LocalServer.INSTANCE; // start local server server.addStatusChangedListener(status -> { if (status.getNewStatus() == LocalServerStatus.STARTED) { // start map image service String mapServiceURL = new File(System.getProperty("data.dir"), "C:\GISData\data\mpks\PointsofInterest.mpk").getAbsolutePath(); mapImageService = new LocalMapService(mapServiceURL); mapImageService.addStatusChangedListener(this::addLocalMapImageLayer); mapImageService.startAsync(); } }); server.startAsync(); } else { Platform.runLater(() -> { Alert dialog = new Alert(AlertType.INFORMATION); dialog.initOwner(mapView.getScene().getWindow()); dialog.setHeaderText("Local Server Load Error"); dialog.setContentText("Local Geoprocessing Failed to load."); dialog.show(); }); } // add view to application window with progress bar stackPane.getChildren().addAll(mapView, imageLayerProgress); StackPane.setAlignment(imageLayerProgress, Pos.CENTER); } catch (Exception e) { // on any error, display the stack trace. e.printStackTrace(); } } /** * Once the map service starts, a map image layer is created from that service and added to the map. *

Yes it is possible, in Qt/c++ at least.  You can call "featureLayer.load();" right before you add the feature layer to the operationalLayers.
