Just started learning OpenLayers 4 and I'm trying to display a simple WMS layer from GeoServer as a web map. I'm not having any luck. If I use a request for OpenStreetMap layers (ie. ol.source.TileWMS) it works, but using ol.source.TileWMS to connect to my GeoServer layers doesn't seem to work. Teh web page is blank and there's not even a box or zoom function. I'm not sure if its my code or if I need to configure GeoServer somehow. Its on a local host, same machine.

The layer properties are:

workspace: basic, layer:roads, EPGS:28356, GeoServer URI for the workspace (not sure if this matters):http://localhost:8080/geoserver/basic

The code is:

<!DOCTYPE html>
    <link rel="stylesheet" href="https://openlayers.org/en/v4.0.1/css/ol.css" type="text/css">
    <script src="https://openlayers.org/en/v4.0.1/build/ol.js"></script>
    <div id="map" class="map"></div>
      var layers = [
        new ol.layer.Tile({
            extent: [429899.9375,6535534.0,509027.46875,6626038.5]
            source: new ol.source.TileWMS({
                url: 'http://localhost:8080/geoserver/basic/wms',
                params: {'LAYERS': 'basic:roads', 'TILED': true},
                serverType: 'geoserver'
      var map = new ol.Map({
        layers: layers,
        target: 'map',
        view: new ol.View({
          center: [484200,6559400],
          zoom: 15

Some more information; the layer preview URL shows http://localhost:8080/geoserver/basic/wms?.....: when http://localhost:8080/geoserver/basic/wms?request=GetCapabilities is entered there is a long screen of XML: and when the developer console is used to check for JavaScript errors, the line source: new ol.source.TileWMS({ is highlighted. If I delete the extents line out of the code, that error is gone (but the map still doesn't​ work).

  • There's nothing recorded in the logs. And you're right, its ol4, I didn't even realise there was a 4!

  • I have Geoserver 2.10.1. In the layer preview URL its localhost:8080/geoserver/basic/wms (plus all the other text after the ?).... I did just notice in the page source code, its pointing to localhost:8080/geoserver/openlayers3/ol.css and ...ol.js, would it be because my code is trying to use the openlayers4 css and js libraries?

  • Openlayers 4 code should be identical to Openlayers 3 in 99.9% of cases. Commented Apr 4, 2017 at 5:42
  • Do you get a long scree of XML if you load up localhost:8080/geoserver/basic/wms?request=getcapabilities (on the localhost)? Commented Apr 4, 2017 at 5:44
  • There is a long screen of xml, and this error is highlighted in the developer console: source: new ol.source.TileWMS({

My solution is based onGeoserver 2.12.1 using openlayers 4.6.4

 var wmsPorts =
                      new ol.layer.Image({
                              source: new ol.source.ImageWMS({
                              url: 'http://localhost:8080/geoserver/wms',
                              params: {'LAYERS': 'ancient_ports' ,
                              serverType: 'geoserver'
              }) ;

This access a wms layer called ancient ports


I had the same issue. I'm working with geoserver 2.11.1 and I had to use ows at the end instead of wms. In your case the url should look like this:

url: 'http://localhost:8080/geoserver/basic/ows'

Further I also don't use the extent.


Just remove this section and your code will work perfectly. I had the same problem as u before.

Remove :

extent: [429899.9375,6535534.0,509027.46875,6626038.5]
