AX2012 How to integrate an asynchronous web service

Hello,

I'm currently trying to enable AX 2012 to handle an external asychronous web service. I'm not shure if I'm using the correct technique.

I followed the instruction under the following article (Walkthrough: Calling an External Web Service from X++ [AX 2012]):

http://msdn.microsoft.com/en-us/library/hh500185.aspx

Because the execution time of the webservice could be longer than the time out ranges, the call could be made asynchronously. But I have no idea how I should receive the response of the web service asynchronously.

Doing the same task within .NET C# I created an eventhandler:

// Eventhandler for Callback

_customerService.RunDecisionCompleted += new MyWebService.RunDecisionCompletedEventHandler(_customerService_RunDecisionCompleted);

publicvoid _customerService_RunDecisionCompleted(object sender, MyWebService.RunDecisionCompletedEventArgs e)

{

if (null != e.Result)

{

// the Resulting Dataset is now available as

DataSet ResultData = newDataSet();

ResultData.ReadXml(

newXmlNodeReader(e.Result));

System.IO.

StreamWriter xmlSW = new System.IO.StreamWriter("C:\\Temp\\Test.xml");

ResultData.WriteXml(xmlSW,

XmlWriteMode.WriteSchema);

xmlSW.Close();

}

// Remove the EventHandler

new MyWebService.RunDecisionCompletedEventHandler(_customerService_RunDecisionCompleted);

}

How could I do the same task be done in AX 2012?

Thanks in advance for any help.
