Map viewer is not able to parse WMS map request

Question

I am experimenting with using Mapviewer to deliver WMS data using the built-in WMS support as documented in appendix D of the manual. The Mapviewer version is 10.1.2.0.2.
Using the following arguments in a browser window, I am able to receive a map image from Mapviewer (I have defined the datasource 'namn_utv' and the map 'SN8307'):
VERSION=1.1.1&
SERVICE=WMS&
REQUEST=GetMap&
STYLES=&
FORMAT=image%2fpng&
SRS=EPSG:4326&
BASEMAP=SN8307&
LAYERS=&
BBOX=5,60,6,61&
WIDTH=524&
HEIGHT=524&
BGCOLOR=0xFFFFFF&
EXCEPTIONS=application/vnd.ogc.se_xml&
DATASOURCE=namn_utv
The problem is that applications able to render WMS layers do not send exactly this format (I have tried ESRIs ArcGIS version 9.1 and Cadcorp SIS Map Browser version 6.2.658). They do not specify the BASEMAP parameter or the DATASOURCE parameter, as they are Mapviewer only.
Is there a way to make Mapviewer accept standard WMS requests such as the one below? Or do I have to re-implement the WMS support myself to be able to handle such requests?
VERSION=1.1.1&
SERVICE=WMS&
REQUEST=GetMap&
STYLES=&
FORMAT=image%2fpng&
SRS=EPSG:4326&
LAYERS=NAMN8307&
BBOX=5,60,6,61&
WIDTH=524&
HEIGHT=524&
BGCOLOR=0xFFFFFF&
EXCEPTIONS=application/vnd.ogc.se_xml
Kind regards,

Rename your datasource to WMS.
Then omit the datasource and basemap names from the request.
See Sec D.2.1
The default data source for a GetMap request is WMS. That is, if you do not specify the DATASOURCE parameter in a GetMap request, it is assumed that a data source named WMS was previously created using the <add_data_source> element (described in Section 7.1.1) in an OracleAS MapViewer administrative request.
