Question

I’m using some 3rd party software that’s failing. Their API is wrapped in a ASP web service.

The call stack tells me that it needs maybe MySQL.Data.DLL or something (not sure exactly) in the correct directory. So I’m wondering where that directory would be. The Web Server is IIS.

Here is the call stack:

  Unable to find the requested .Net Framework Data Provider.  It may not be installed.

       at WebReports.Api.Data.DataObjectBase.GetDataObject(PageInfo pageInfo, Int32 dataSourceId, String objectType, Boolean isSqlSpecific)

       at WebReports.Api.Reports.Report.LoadData(Boolean validate)
       at WebReports.Api.Reports.Report.Load(String reportName)

Above this line is their API, so I can’t inspect it:

       at eWebReportsLETG.ReportURLService.GenerateReportURL(Int32[] list, String m_szWebReportsVirtualDirectory, String m_szWebReportsUrl, String ReportDir, String ReportName, String PkSpecialName, Boolean& Failed) in C:\dev\eWebReports\eWebReportsLETG\ReportURLService.asmx.cs:line 51

Answer 1

I needed to copy MySQL.data.dll to the bin directory of my web service application directory. I also added the config key to the web.config.
