RE: [mapserver-users] MapScript issue in multiple WCF apps (ASP.NET)

Thanks Tamas,
I put together a solution that mimics what I am doing at a very simple level 
and I got it to error fairly easily.

This zip contains an example mapfile and the solution used to reproduce the 
setup. I just put everything in c:\tmp\test. The applications are .NET 4.0 WCF 
endpoints and will install as IIS web services (so obviously you’ll need the 
appropriate software to build/run).
http://dl.dropbox.com/u/649621/WcfMapScript.zip

If you build the solution and then execute the following service requests in 
order, at some point the requests no longer return correct data. Asking for one 
layer will return the other. Sometimes the results vary but usually just mixing 
up the requested layers on the two different services will cause strange 
behavior.

Hi Brian,

Could you provide the sequence of the requests, a mapfile example, that can be 
used to reproduce this problem?
What do you mean by configure them independently? Different application pool 
for each service type?

I have a very strange issue while using MapScript from within some web service 
projects. I have different projects/applications for different services – one 
for each of WCF, WMS, WFS, and WMTS – so we can configure them independently. 
MapScript requests work fine for all of them separately but if I access 
MapScript from one and then another, one of them will not work correctly 
anymore. The requests will return success (result == 0) and the format returned 
is correct but the data is either null or an incorrect image. It doesn’t seem 
to be a threading issue since I can bombard any one of the services with 
asynchronous requests and they are handled fine and the problems don’t 
necessarily come while using the different applications at the same time – just 
one then the other.

 I am using a support project for making the MS requests that is referenced
 by each application (though I tried putting the code directly in each app
 with the same results). Below is a simplified version of the helper utility
 I am using. Is there anything that stands out as being an obvious issue? My
 endpoint applications simply get the query parameters from the url request
 and pass them as the requestParams argument with the appropriate map file.

 namespace MapScript

 {

  public class MapScriptResponse

  {

  public string Format { get; set; }

  public byte[] Data { get; set; }

  public string ErrorString { get; set; }

  public DateTime LastModified { get; set; }

  }

  public class MapScriptUtilities

  {

  /// summary

  ///
  Execute a service request to mapserver through mapscript

  /// /summary

   /// param name=mapFile
 Physical path to the map file on which to make the request/param

  /// param name=requestParams
 List of request parameters/param

  /// returnsThe response from mapscript./returns

   public static MapScriptResponse ServiceRequest(string
  mapFile, Dictionarystring, string requestParams)

  {

   MapScriptResponse response = new
 MapScriptResponse();

   mapObj map = new mapObj(mapFile);

   OWSRequest owsRequest = new OWSRequest();

   Dictionarystring, string.Enumerator
  en = requestParams.GetEnumerator();

   string paramName = ;

   string paramValue = ;

   while (en.MoveNext())

   {

paramName = en.Current.Key;

paramValue = en.Current.Value;


 owsRequest.setParameter(paramName, paramValue);

   }

   mapscript.msIO_installStdoutToBuffer();

   int resultCode = map.OWSDispatch(owsRequest);

   if (resultCode == 0)

   {

response.Format = mapscript
 .msIO_stripStdoutBufferContentType();

response.Data = mapscript
 .msIO_getStdoutBufferBytes();

   }



   return response;

  }

  }

 }



 Any help would be greatly appreciated.
