Hi I am trying to develop a consumer web service on webMethods .
I got the wsdl from Service provider and the service is developed in C#.
Whenever i sent a request to service provider using web service connector, i am getting a soap fault.

soap:Faultsoap:ServerSystem.Web.Services.Protocols.SoapException: Server was unable to process request. —> System.NullReferenceException: Object reference not set to an instance of an object. at Allegro.DsHelper.SetSqlTracing(DataSet ds, Boolean tracing)
at Allegro.Credit.WS.CreditAnalysisWS._RetrieveCreditAnalysis(CreditAnalysisDS creditAnalysisDS, String tableNames, DateTime Valuationtime, SelectCriteria criteria, String currency, String creditformat, String creditsimulation)
at Allegro.Credit.WS.CreditAnalysisWS.RetrieveCreditAnalysis(CreditAnalysisDS creditAnalysisDS, String tableNames, DateTime Valuationtime, SelectCriteria criteria, String currency, String creditformat, String creditsimulation)
— End of inner exception stack trace —</soap:Fault>

Can any body help me with this.?

Thanks,

are you passing the proper parameters for this call?
To fully understand the error, you sure need to talk to the partner you are connecting to.
