SSIS web service task, can't execute web service

Question

Hi I have a web service that is called from my ssis.

Used to work fine in test mode, when moved to live environment I get the error :

[Web Service Task] Error: An error occurred with the following error message: "Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebserviceTaskException: Could not execute the Web method. The error is: Object reference not set to an instance of an object.. at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebMethodInvokerProxy.InvokeMethod(DTSWebMethodInfo methodInfo, String serviceName, Object connection) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTaskUtil.Invoke(DTSWebMethodInfo methodInfo, String serviceName, Object connection, VariableDispenser taskVariableDispenser) at Microsoft.SqlServer.Dts.Tasks.WebServiceTask.WebServiceTask.executeThread()".

We are using a proxy to access the web. Could this be a proxy problem. how to solve ?

Thanks

Answer 1

To help diagnose this, you might try using a script task and adding a Service Reference or Web Reference to the web service. Call the service within a try/catch block and log ex.ToString() if you get an exception. That way, you'll be sure to have all the details, and you can post them here in an edit to your question.

Answer 2

It was simple proxy issue.

Don't forget to configure the proxy tab in your Http Connection Manager
