I m currently communicating with an external SOAP service within AX using the a service reference and the generated .NET class. Everything is working out greatly with the exception of how to handle SOAP faults. Ideally, this doesn t happen, but sometimes the SOAP server (which I control as well) throws a SOAP fault with a "code" and a "message". Some examples of codes and their respective messages:
- "INVALID_API_KEY" / "An invalid API key was used."
- "INVALID_CUSTOMER_ID" / "An invalid customer Id was passed (%d)".
These error codes are defined in the WSDL, so when these faults are thrown I can naturally pass back some sanitized message to the user. Unfortunately, I m having a problem drilling down through X++ to figure which SOAP fault has been thrown so that I can display back a sanitized explanation of failure back to my user. Currently my code looks like:
try
{
new InteropPermission(InteropKind::ClrInterop).assert();
// ... code making SOAP calls
CodeAccessPermission::revertAssert();
}
catch(Exception::CLRError)
{
warning(AifUtil::getClrErrorMessage());
}
This handles the SOAP fault well enough, the error it produces is the following: " Type System.ServiceModel.Channels.ReceivedFault in assembly System.ServiceModel, Version=3.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089 is not marked as serializable."
I have tried drilling down the base .NET classes, but the ServiceModel (and subsequently) the other classes for translating the SOAP fault (FaultException down the class ladder) into a human readable message are obscured.
Can anyone lend me some insight on how best to get at the actual fault code/message? Thanks!
