Problem getting the map

angelurbano_rogel — Tue, 03 Sep 2013 11:16:28 GMT

I have a problem with the following line of code, I use a SOE.

 public static IMap getMyMap(IServerObjectHelper serverObject) throws IOException{
  
  IMapServer2 mapServer_2 = (IMapServer2) serverObject.getServerObject();  
  IMapServerObjects2 serverObjs_2 = (IMapServerObjects2) mapServer_2;  
  IMap map = serverObjs_2.getMap(mapServer_2.getDefaultMapName());
  
  return map;
 }

when I run it, I get the following error.

AutomationException: No such interface supported

Can anyone help?, What am I doing wrong?

Thank you.

If you are working in 10.1 or 10.2, you can't do that anymore.

Scroll down to the SOE section and take note that IMap is not supported.

http://blogs.esri.com/esri/arcgis/2011/04/27/considerations-for-arcgis-server-developers-a-look-toward-10-1/

SOE development requires knowledge of ArcObjects,.NET or Java, and Web service communication technologies such as REST and SOAP. The ArcObjects SDK has several samples that you can examine, both for Java and .NET.

If you plan on developing new SOEs, keep in mind that in ArcGIS Server 10.1 you will be required to analyze your map documents before publishing them and fix any errors that appear. Thus, one of the things you can do to get your SOE�??s ready for 10.1 is to make sure they work against MSDs at 10.0. Building SOE�??s on top of MSD based map services with ArcGIS Server 10.0 is perfectly possible. The biggest requirement is that you avoid using MXD-specific interfaces (such as IMap, ILayer, anything to do with page layouts, and so on). Here is a blog post describing how you can use IMapServerDataAccess to get to the data sources of an MSD-based map service.

Thanks for the reply ldonahue.
I'm working with version 10.1.
But if you can not access the IMap within a SOE, neither can access the published FeatureLayer in service?

Sadly, no. Not the way you were doing it before.

Before you get that far, you can't even use the same connection method you had before in your SOE either. Connecting to ArcGIS Server using SOE does not allow servername, username and password anymore.

I have a big problem.
Is there any way to know if they are visible or not the fields in a layer? and if it has defined a QueryDefinition?

The blog link I provided indicates we can't do anything mxd related at 10.1 because of the optimized map services. You have two choices for SOE, the REST API or the SOAP API.

In the SOAP API, I see a QueryFilter, but I don't see QueryDefinition.

I also see a Field in the SOAP API, but it doesn't have a visible property.

LayerDescription
http://resources.arcgis.com/en/help/soap/10.2/01vp/01vp00000105000000.htm

DefinitionExpression:
The LayerDescription includes a DefinitionExpression. A DefinitionExpression can be set on a layer in order to limit layer features available for display or query. This only applies for the request and does not replace the definition query set in the source map.

So close...

Idonahue Thank you, you helped me a lot.
In the end I managed to get the information required of layer
1. ILayerDescription.getDefinitionExpression () to get the layer DefinitionQuery
2. IMapLayerInfo.getFields () gives me all the fields of the layer visible if I compare with the featureClass.getFields () can identify the fields are visible and not visible.
