WmtsLayer loading exception

KarlBarkmann — Sat, 11 Dec 2021 07:38:20 GMT

Hello,there.Sorry about my poor english.

I am adding a wmtslayer by using the following code.

But there is a exception occurs while WmtsService loading.

The Exception says:Invalid XML.: Parser couldn't move inside Keywords.

Here's the call stack:

在 System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw()
在 System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)
在 System.Runtime.CompilerServices.TaskAwaiter.GetResult()
在 ArcGISRuntime.WPF.Samples.WMTSLayer.WMTSLayer.<Button2_Click>d__2.MoveNext() 位置 C:\Workbench\sources\arcgis-runtime-samples-dotnet-master\src\WPF\ArcGISRuntime.WPF.Viewer\Samples\Layers\WMTSLayer\WMTSLayer.xaml.cs:行号 72

Any idea why this exception happens?

You can find the capacities xml from attachment.

             try
            {
                // Define the Uri to the WMTS service
                var myUri = new Uri("http://xxxxx:8080/geoserver/gwc/service/wmts");

                // Define a new instance of the WMTS service
                WmtsService myWmtsService = new WmtsService(myUri);

                // Load the WMTS service 
                await myWmtsService.LoadAsync();

                // Get the service information (i.e. metadata) about the WMTS service
                WmtsServiceInfo myWMTSServiceInfo = myWmtsService.ServiceInfo;

                // Obtain the read only list of WMTS layer info objects
                IReadOnlyList<WmtsLayerInfo> myWmtsLayerInfos = myWMTSServiceInfo.LayerInfos;

                // Create a new instance of a WMTS layer using the first item in the read only list of WMTS layer info objects
                WmtsLayer myWmtsLayer = new WmtsLayer(myWmtsLayerInfos[0]);

                // Create a new map
                Map myMap = new Map();

                // Get the basemap from the map
                Basemap myBasemap = myMap.Basemap;

                // Get the layer collection for the base layers
                LayerCollection myLayerCollection = myBasemap.BaseLayers;

                // Add the WMTS layer to the layer collection of the map
                myLayerCollection.Add(myWmtsLayer);

                // Assign the map to the MapView
                MyMapView.Map = myMap;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I'm having the same problem as you. Did you achieve to solve it?

Thanks

Karl Barkmann‌ — We have identified several compatibility problems between ArcGIS Runtime and newer GeoServer versions. Looks like the service you are using is affected by the same issues. You can find detailed technical discussion and some workaround ideas here: Geoserver 2.14 with ArcgisRuntimeSDK 100.4

We've prepared several GeoServer compatibility improvements and they will be available in a Runtime update in the near future. I will update this discussion when it's released.

Good news — ArcGIS Runtime 100.5.0 was released this week! It makes several improvements to GeoServer/GWC compatibility. Upgrading to this version should resolve the WMTS problems that you are experiencing. Please let us know how it goes!
