I am working on a ArcGIS Server now. I referred http://resources.arcgis.com/en/help/main/10.1/index.html#/A_quick_tour_of_using_a_service_in_ArcGIS_..., the approach: Finding the URL to a geoprocessing service. I observed that all of the REST URL's work fine but all of the SOAP URL's get Error 400. Why I could not get the SOAP services? What parameter(s) should be setup for SOAP URL's in additional to the REST ones? Thanks if you can provide your experience.
