SoapException: The session identifier is missing

    #191587

    I keep getting this error when I try to generate a report using the web service.

    This was working previously, until I attempted to add parameter information.  Here's my code:

                localhostExec2005.ReportExecutionService rs = new localhostExec2005.ReportExecutionService();

                rs.Url = globalData.ReportingServicePath + "/ReportExecution2005.asmx";

                System.Net.NetworkCredential nc = new System.Net.NetworkCredential("aaaaaa", "xxxxxx");

                rs.Credentials = nc;

                localhostExec2005.ParameterValue[] rsParams = new localhostExec2005.ParameterValue[4];

                rsParams[0] = new localhostExec2005.ParameterValue();

                rsParams[0].Name = "clientID";

                rsParams[0].Value = "6";

                rsParams[1] = new localhostExec2005.ParameterValue();

                rsParams[1].Name = "fiscalYear";

                rsParams[1].Value = "2004";

                rsParams[2] = new localhostExec2005.ParameterValue();

                rsParams[2].Name = "bID";

                rsParams[2].Value = "260";

                rsParams[3] = new localhostExec2005.ParameterValue();

                rsParams[3].Name = "DirectCostTitle";

                rsParams[3].Value = "test";

                rs.SetExecutionParameters(rsParams, "en-us");

                localhostExec2005.ExecutionHeader execHeader = new localhostExec2005.ExecutionHeader();

                localhostExec2005.ExecutionInfo rpt = rs.LoadReport("/TestReports/TestReport01", null);

                rs.ExecutionHeaderValue = execHeader;

                rs.ExecutionHeaderValue.ExecutionID = rpt.ExecutionID;

                string Extension = "";

                string MimeType = "";

                string Encoding = "";

                localhostExec2005.Warning[] warnings = null;

                string[] streamIDs = null;

                byte[] rptStream = rs.Render("PDF", null, out Extension, out MimeType, out Encoding, out warnings, out streamIDs);

    I just can't seem to find any decent documentation or examples in how to do this.  Can anyone help?  Thanks

    I actually discovered the problem.

    The SetExecutionParameters method had to be called after the report was loaded:

    localhostExec2005.ExecutionInfo rpt = rs.LoadReport("/TestReports/TestReport01", null);

    rs.SetExecutionParameters(rsParams, "en-us");

    Now it works fine.  However, I am still somewhat unclear about what's happening here, and if anyone knows a good resource or tutorial about this, I would really appreciate it!
