I have published a service to AGS and enabled WMS as an option. When making requests to the WMS a layer with polygons is not displaying as transparent. In the mxd from which the service has been published, the polygon is set to a solid fill with the transparent setting set to 50% in the display tab on layer properties. When viewing the wms request in a web browser the polygon is not transparent and also viewing it in a jsapi it is also not transparent.
Is there a trick to get WMS to obey the transparency settings from the mxd the service is published from ?
