Question

I’m using SSRS 2008 (NOT R2)

I have a report deployed to a dev server, I’m trying to render the report as a pdf by calling the execution service.

The error I am getting is
This operation is not supported on a report server that runs in native mode. —> Microsoft.ReportingServices.Diagnostics.Utilities.OperationNotSupportedNativeModeException: This operation is not supported on a report server that runs in native mode.

Two things I notice: one is that web service wsdl shows LoadReport having two parameters – report path and history id, but when I generate a service reference for the ReportExecution2005.asmx, the LoadReport method has 5 parameters: trusteduserheader, reportPath, historyid, serviceinfoheader, and executionheader

I have tried adding the service reference with and without ?wsdl at the end of the url but the result is the same

Here’s the code I’m using:

ReportExecutionServiceSoapClient rs = new ReportExecutionServiceSoapClient("ReportExecutionServiceSoap", "http://xxx:80/ReportServer/ReportExecution2005.asmx");            
        rs.ClientCredentials.Windows.ClientCredential = new NetworkCredential("aaa", "aaa", "aaa"); 

        rs.ClientCredentials.Windows.AllowedImpersonationLevel = TokenImpersonationLevel.Impersonation;



 // Render arguments

    byte[] result = null;
    string reportPath = "/Invoices/InvoiceStandard";
    string format = "PDF";
    string historyID = null;
    string devInfo = "";

    // Prepare report parameter.

    ParameterValue[] parameters = new ParameterValue[3];

    parameters[0] = new ParameterValue();
    parameters[0].Name = "PartyID";
    parameters[0].Value = "19758";
    parameters[1] = new ParameterValue();
    parameters[1].Name = "Contract";
    parameters[1].Value = "17703"; // June
    parameters[2] = new ParameterValue();
    parameters[2].Name = "FinancialPeriod";
    parameters[2].Value = "MAR-2012";
    string encoding="";
    string mimeType="";
    string extension="";
    Warning[] warnings = null;
    string[] streamIDs = null;

    ExecutionInfo execInfo = new ExecutionInfo();
    TrustedUserHeader trusteduserHeader = new TrustedUserHeader();
    ExecutionHeader execHeader = new ExecutionHeader();
    ServerInfoHeader serviceInfo = new ServerInfoHeader();


    execHeader = rs.LoadReport(trusteduserHeader, reportPath, historyID, out serviceInfo, out execInfo);

    rs.SetExecutionParameters(execHeader, trusteduserHeader, parameters, "en-us", out execInfo);

    try
    {                
        rs.Render(execHeader,
                    trusteduserHeader,
                    format, 
                    devInfo, 
                    out result,
                    out extension, 
                    out encoding, 
                    out mimeType, 
                    out warnings, 
                    out streamIDs);
    }

Is this report loaded from some front end or is it loaded from DLL? To me it looks like you are using ASP.net Application. In this case you could use reportViewer object to pull the report for you all the heavy lifting can be done by the ReportViewer and you can then just save the file as PDF
using something like this

 reportViewer.ServerReport.ReportServerUrl = new Uri(Config.ReportServerURL);
 reportViewer.ServerReport.ReportPath = String.Format("{0}/{1}", Config.ReportServerEnvironment, reportName);
 reportViewer.ServerReport.ReportServerCredentials = new ReportsCredentials(Config.ReportServerUser, Config.ReportServerPassword, Config.ReportServerDomain);

reportViewer.GetDocumentStream(SSRSFormatType.Pdf, documentName);

Here reportViewer is the reference to ReportViewer object on the screen.
