Problem using WMS service in Flex Viewer 2.1

PaulHeinrich — Tue, 28 Sep 2010 19:34:49 GMT

Hello,

I'm trying to use the Arizona Geologic Survey geologic map service in a Flex Viewer project. The service is a WMS service. When I add it as a operational layer it does not display. I'm wondering if there is a problem with the service or the way in which I'm referencing it?

Here's the service link..

http://services.azgs.az.gov/arcgis/services/OneGeology/AZGS_Arizona_Geology/MapServer/WMSServer

Here's the web site for the service.. http://www.azgs.state.az.us/services_azgeomap.shtml

and here's my tag from my Flex Viewer project..

<layer label="Arizona Geology" type="dynamic" visible="false" alpha="1" url="http://services.azgs.az.gov/arcgis/services/OneGeology/AZGS_Arizona_Geology/MapServer/WMSServer"/>

cheers, Paul

The Viewer doesn't support wms services yet. (The API does as of 2.1.)

You can try using their ArcGIS REST service here instead:
http://services.azgs.az.gov/arcgis/rest/services/OneGeology/AZGS_Arizona_Geology/MapServer

You'll need to use a proxy though since they don't have a cross domain policy file at:
http://services.azgs.az.gov/crossdomain.xml

Hi Paul,

WMS is not supported in "ready to deploy" ArcGIS Flex Viewer 2.1.
WMS support will be added to viewer in in future release.

For list of supported layer types see: http://help.arcgis.com/en/webapps/flexviewer/help/Default.htm#CSHID=layer_tag.htm|StartTopic=layer_tag.htm

If you are working with the source, then you can take advantage of ArcGIS API for Flex 2.1 to add support for WMS see sample at: http://help.arcgis.com/en/webapi/flex/samples/index.html?sample=WMS
and

I dropped the link you pointed out into my application and it works great on the desktop. Will I need a proxy to run it from my server? I've never set that up, so I'm wondering what I'll need to do.

cheers, Paul

and
http://help.arcgis.com/en/webapi/flex/apiref/com/esri/ags/layers/WMSLayer.html

Is there an easy way to integrate this so that a wms could be added to the operational layers. Something like creating a new case (under "private function addLayerToMap" in MapManager.mxml)?

I attempted this, but it did not work. I am comfortable with writing python automation scripts, but am new to flex coding.

case "wms":
{
var webmsLayer:WMSLayer = new WMSLayer(url);
webmsLayer.alpha = alpha;
webmsLayer.id = label;
webmsLayer.name = label;
webmsLayer.token = token;
webmsLayer.visible = visible;
if (autoRefresh > 0)
{
setInterval(webmsLayer.refresh, autoRefresh * 1000);
}
if (visibleLayers)
{
var vizLayers:Array = visibleLayers.split(",");
for (var i:int = 0; i < vizLayers.length; i++)
{
vizLayers = Number(vizLayers); // convert to Numbers
}
webmsLayer.visibleLayers = new ArrayCollection(vizLayers);
}
if (proxyUrl && useProxy)
{
webmsLayer.proxyURL = proxyUrl;
}
if (operationalLayer)
{
layerObject.layer = webmsLayer;
}
map.addLayer(webmsLayer);
break;
}

Thanks Dasa,

I've installed the proxy.ashx and proxy.config and added a useproxy="true" to my geology operational layer.

My proxy.config looks like this...

<?xml version="1.0" encoding="utf-8" ?>

<ProxyConfig mustMatch="true">
<serverUrls>
    <serverUrl url="ttp://services.azgs.az.gov/arcgis/rest/services/OneGeology/AZGS_Arizona_Geology/MapServer"
               matchAll="true"></serverUrl>
    </serverUrls>
</ProxyConfig>

and my operational layer look like this...

<layer label="Arizona Geology" useproxy="true" type="dynamic" visible="false" alpha="0.5" url="http://services.azgs.az.gov/arcgis/rest/services/OneGeology/AZGS_Arizona_Geology/MapServer"/>

but the layer still does not display in my application.

Do I need to add "esri.config.defaults.io.proxyUrl = "proxy.ashx";" in my application? If so, where should I set it?

cheers, Paul

You need to add <httpproxy>proxy.ashx</httpproxy> to the root (like the title) of your config.xml to tell the Viewer what the url to the proxy is.

You're also missing the 'h' in http in the url on your serverUrl in the proxy.config. You don't have to give it the full url. You can just use the start like this "http://services.azgs.az.gov/".

Hi All,

Please give me clear instructions to add map services to flexviewer 2.1; I whant to add in <operationallayers>...</operationallayers> a wms service that connect to geoserver 2.0.2, something like:

<layer label="Map2" type="dynamic" visible="true" alpha="1" url="http:localhost:8080/geoserver/wms"/>

or

<mapservice label="map2" type="wms" visible="true" alpha="1" format="image/png" layer="map2" format_options="antialias:none" crs="EPSG:900913" icon="com/esri/solutions/flexviewer/assets/images/icons/i_shuttle.png">http://localhost:8080/geoserver/wms?</mapservice> ---this was for flex 1.3 and its working, but i whant to use 2.1;

Please tell me what file i have to modify, to add wms service to work;

Thank you

I have the same question as adrian. specifically, I am trying to see if I can get layers from this WMS service to show up in 2.2 as an operational layer.

http://donmeltz.dyndns.org:8080/geoserver/wms?service=wms&version=1.1.1&request=GetCapabilities

I tried but can't seem to get anything to display. Any help on this would be appreciated. This is what I currently have:

[HTML]          <layer label="Counties"
                   type="wms"
                   imageformat="openlayers"
                   visible="false"
                   visiblelayers="StockportWatershed:CountyBoundaries"
                   url="http://donmeltz.dyndns.org:8080/geoserver/wms?service=wms&version=1.1.1&request=GetCapabilities"
                   skipgetcapabilities="true"
                   version="1.1.1"/>[/HTML]

Thanks,
Eric

Eric,

The url should not include the service, version or request parameters. You could configure it more like this:

<layer label="Counties"
                   type="wms"
                   visible="false"
                   visiblelayers="StockportWatershed:CountyBoundaries"
                   url="http://donmeltz.dyndns.org:8080/geoserver/wms"
                   skipgetcapabilities="true"
                   version="1.1.1"/>

If you try adding this to the default config.xml it still won't work though because the server returns this error "Error occurred decoding the espg code EPSG:102100". You can see this if you use a tool like HttpFox or Fiddler.

This error means that the service doesn't support the 102100 spatial reference (SR). The capabilities show that it does support the equivalent SR of 900913 as well as 4326 and 2260. In the next release you'll be able to configure the layer to use it's own SR instead of using the map's SR so then you could set it to use 900913.

In the current 2.2 release you'll need to change your map to only use 4326 or 2260 layers if you want to use this WMS service.

I thought that visiblelayers had to use the numeric format (e.g. visiblelayers="0,1,2" to show the first three layers, identified as queryable=1, etc.). Not so?

Re: Problem using WMS service in Flex Viewer 2.1

DasaPaddock — Wed, 16 Feb 2011 18:52:19 GMT

Jon,

WMS uses strings for layer names instead of numbers.

Jon,

WMS uses strings for layer names instead of numbers.

Strange, at least for consuming ArcGIS Server map services in the WMS format, when I use visiblelayers="0,1,2" it works for me in FlexViewer 2.2. Maybe WMS from other servers wouldn't work that way though.

Re: Problem using WMS service in Flex Viewer 2.1

DasaPaddock — Wed, 16 Feb 2011 19:04:11 GMT

Yes, the names of the Layers in an ArcGIS Server WMS service are still numbers.

e.g.

http://sampleserver1.arcgisonline.com/arcgis/services/Specialty/ESRI_StatesCitiesRivers_USA/MapServer/WMSServer?service=WMS&request=GetCapabilities

Has:
<Name>0</Name>
