Don't know what I'm doing wrong; trying to load layers from ArcGIS Server into web using 'ArcGISDynamicMapServiceLayer', can see the basemap but not the layer.

see code below:




<link rel="stylesheet" href="https://js.arcgis.com/3.19/esri/css/esri.css">

<script src="https://js.arcgis.com/3.19/"></script>



 // Add data from ArcGIS Server

var featureLayer = new esri.layers.ArcGISDynamicMapServiceLayer("https://herse.chelmsford.chelmsfordbc:6443/arcgis/rest/services//Boundaries/MapServer/2");


  • There is an extra "/" in the path for the feature layer url (.../services//Boundaries/...). Did you see any errors in your console? Also, why are you loading the FeatureLayer module but using "esri.layers.ArcGISDynamicMapServiceLayer"

You are trying to add a Feature Layer using a ArcGISDynamicMapServiceLayer, which is not the right class. Use FeatureLayer instead (see the example in the ESRI Documentation)

var featureLayer = new FeatureLayer("https://herse.chelmsford.chelmsfordbc:6443/arcgis/rest/services//Boundaries/MapServer/2");

If you want to really add a Dynamic Map Service, instead of a Feature Layer, then check this out.

Note: You need first to create a Map object before add the feature layer to it. I think you did it, because you can see the basemap, but just in case...

  • Thanks Katah, I do have mybase map. I have made changes still unable to see the layer; // layer from server. var featureLayer = new FeatureLayer("https:\\herse.chelmsford.chelmsfordbc:6443/arcgis/rest/services/Ordnance_Survey/Boundaries/MapServer/1"); map.addLayer(featureLayer); May 18, 2017 at 11:49
  • @MatildaAjiri Please check the following: - 1 Try to add first a "sample" layer from ArcGIS. For example this. Is it working? - 2 Check the type of your layer. For that go to your Layer URL and the fourth property should be the type. Which type of Layer do you have?
